Hi, I’m Krista! I make math courses to keep you from banging your head against the wall. ;)
Math class was always so frustrating for me. I’d go to a class, spend hours on homework, and three days later have an “Ah-ha!” moment about how the problems worked that could have slashed my homework time in half. I’d think, “WHY didn’t my teacher just tell me this in the first place?!”
So I started tutoring to keep other people out of the same aggravating, time-sucking cycle. Since then, I’ve recorded tons of videos and written out cheat-sheet style notes and formula sheets to help every math student-from basic middle school classes to advanced college calculus-figure out what’s going on, understand the important concepts, and pass their classes, once and for all.

its 3 am im so lost
man same
chodíš na FIT?
Lost watching Krista? If you don't get this stuff with her, drop the class and check your math background.
@Bazinga! 6 feet under ground
Agreed. I am lost as hecc...
this is the complicated version of how to solve this i was looking for, thanks!
Absolutely kick-ass video... a million times more informative than any of my professors.
This was so helpful and much easier to understand than my professor! Thank you!!
Krista, you are so brilliant, explain steps so well, and are so very nice as well. This is true with all of your videos. Many thanks to you.
Geez, I love how you went into detail and helped me know why so I can actually remember it! Thank you, I subbed
Awesome, thank you so much! :D
This was a very thorough explanation. Great job! Thanks.
One of the best videos on this I’ve ever seen. Thank you so much!
thank you sooo much! you helped a bunch! You explain everything so well too!
Really well done, excellent explanation of steps in a clear and concise manner. Thanks!
+Sky DeBaun You're welcome, I'm so glad you liked it!
Krista, you're a saint! I watched your videos for help with Calc 1 and now I'm in Calc 3. Thank you for being part of my learning!!
I'm honored! And congrats on making it all the way to Calc 3, you're killing it! :D
This only one question explains me many concepts. This is really a nice video. Hope you upload more videos like this. Thankyou very much 👍🏻
You're welcome, Soniya, I'm so glad you liked it! :)
thank you, its very easy to understand your solution unlike many other videos.
Thank you so much for this! I find this way easier to understand than the triangle/parallelogram rule
+Alex Yokiel You're welcome, I'm so glad it helped!!
Thanks a lot!
The video was clear throughout and helped me understand resultants much better (I am a 9th grader)
You're welcome, I'm so glad it helped!
wow this is cool, really helped me for my homework
Thank you so much, I watched several videos and this was the easiest to understand
Glad it could help!
That was very helpful thank you Krista!
You can make it simpler by using table for x and y components. Then add all x and y separately (don’t forget the signs) then get the theta by getting the arctan of y over x. Simple as that.
Thanks, it's very helpful. I spent three days solving one sum related to resultants but I couldn't, but now I can do it in few minutes thanks🤘💪
You're welcome, Demon, I'm so glad it helped!! :D
Good teachers are underrated. You are one. Thanks alot.
beautifully explanation....I was so confused between these two terms and you, mam clear my confusion.you will be nice professor...or a good teacher.thank you so much madom.😃☺🙌
You're welcome, I'm so glad it helped!
Thanks for this, Ive been searching for a tutorial this clear and concise on this topic!
THIS HELPS SO MUCH!!!
You saved my life!!!! Thank you so much
oh god thank you so much! I've been stuck on this for forever
You're welcome... I'm so glad it helped!! :D
Thank you so much-I was stuck on this problem but not anymore! :)
Yay! That's so awesome! Thanks for letting me know.
Thank you so much it really helped me in both mechanics and physics
thanks once again
+sachi codo You're welcome, I'm so glad it helped!
Really I can get help from your lessons.... thank you....🙂🙂🙂
What if the two force vectors cant make an easily calculable 90* triangle for arctan to be viable? Like what if neither vector lies on an axis? (Just for calculating angle)
Hey, thanks for the video very informative.
I want a video of , how to break any vector quantity in two components ( Sin and cos components) .
thanks again
Great explanation but finding the angle of the resultant force may sound confusing. You can just do tan theta = (100sqrt3)/(-200) then you get a negative number but add 180 degrees. That gives you the same answer instead of finding an angle we don't need to worry about.
How did you calculate the π-arctan √3/2 that the resulting answer is 139.1°?
same question noww
I didn't understood that may be that's because of my weak mind
Same
im trying to stop at the first line. so like how do i expand working cuz my question asks to prove that F1 equals blah but your first line is legit my RTP so what do i do to come to that conclusion at a slower rate?
Thank you, this really helped me!!!!
Very educational 👌
Does this way of calculating resultant force works with all sort of resultant forces even for 3 vectors
This was extremely helpful, thank you!
You're welcome, Michael, I'm so glad it helped! :)
Amazing explanation!!!! I love this Soo much :-P
Best math teacher on CZcams.
thanks a lot, can you please help me how to know if i will add or subtract 360 degrees or 180 degrees in determining direction measured clockwise or counter clockwise?
yeah i gotchu
This video saved my life!
When calculating the horizontal and vertical component of the F2 why do u use 180 degrees . Isn't it supposed to be 60 ? please explain me and thanks again good job and keep up :)
I'm sure you know this now, but 60° is the angle of F1, not F2. We always measure the angle of a force from the positive X-axis.
you are really an awesome teacher ...........keep up the good work
thank you very much!
question... what would you do if on both F1 and F2 you have square roots because the problem I am doing has that
Thank you so much for your detailed explanation
You're welcome! I'm glad it could help!
This video helped me a lot thanks
thank u for giving a detailed explanation.. I have my weekend exam by tomorrow. I hope this will help me..
I hope it will too! Good luck on your exam!
Thank you. I was trying to figure this out for at least 4 hours
You're welcome, Tariq, I'm so glad this helped!! :D
Is the purple angle, the angle which the resultant makes with the positive y-axis?
Thank you for sharing this knowledge.
I'm happy to help! :)
bloody hell this was good. Thank you!!
You're welcome, I'm so glad you liked it! :D
GREAT DETAIL!! :) thanks
You're welcome, Diana, I'm so glad it helped! :)
Nice explanation 👍
you goooooooo girllllllllll amazing video + thumbs up for the voice
Could you use the dot product too solve this as well?
This is literally so much more confusing maybe it’s because I live in the lab down under 🙃
What if angle is not given only resultant force and it's components and we have to find angle? What can we do
Thanks so much!
How come its not negative cosine, when calculating for F2, since it is in the opposite direction?
Inverse cosine is used to isolate the x when you are trying to figure out the angle
Magnitude cannot be negative. |-300|cos(180)
really helped a lot thx so much
Great video. Thanks a lot! ❤❤
Thanks!
THANK YOU VERY MUCH MS!
You're very welcome, Popomp!
I think we have to find angle of only theta not the purple on because belongs to our resultant (am i wrong or not plzzzzzzzzzz answer)
Thanks. Krista. God bless.
super helpful, thank you so much : )
Glad I could help!
Is there any advantage of utilizing this component force calculation over the law of Cosine and law of Sine method?
1972hattrick i depend on what you understand best put i prefer this method cause i understand it clearly
Very helpful, thanks
Dennis Kichamu You're welcome, so glad I could help!
Sorry please but why is 300cos being multiplied by ,180 when angle on a straight line is 180 and 180- 60=120
Thanks, excellent video!
+Hayden Micallef Thank you so much!
Krista Queen !
i love you teacher but the problem is the angel is different from what i had studied. i think it is tan inverse Fy over Fx !?
How to find theta between F1 n F2 if 60° isn't given to us please🙏🙏
What if you dont have any angle for f2 because its not exactly 180⁰?
Excellent explanation
Thanks, Adwai! :)
ma,am your lectures help a lot , thnx alot
Glad you like them!
Thanks, helped me a lot. Forgot how to find the theta direction.
You're welcome, I'm so glad it helped!
The resultant of 2 vectors is 105 N.Find the two forces acting at an angle of 40 degree, if F1 is 20 less than F2? Find also the angle it makes for both F1 and F2?
i really just like yo explanation,well done
+weston mulenga Thanks, I'm glad you liked it!
Why are we relating the f^2 angle to the positive x axis ?
very helpful, thank you so much
Glad I could help!
Find the magnitude and direction of two vectors 15N and 20N acting as an angle of 60degree to each other using both graphical and analytical methods
Your handwriting is so nice
Professor, I need help with a specific question
Excellent, Thanks .
You're welcome, G P, I'm glad you liked it! :)

n which app u r using for the video it's good ,
+d2c I'm glad it helped! I'm using a program called Sketchbook.
thanks for the reply
much detail . I like it ^^
Thanks, I'm glad you liked it!
is this a rectangular method?
Thank you so much!!!!!!!
You're welcome, glad you liked it! :D
Nice concept
Great video thanks
Thanks, George! So glad you liked it! :)
how do you write so neat. what device are you using to write
I use a Wacom pen tablet. :)
no need for the 3oo to be negative because it is going opposite way?
thanks a lot
your course is just too nice because i'm just from learning something from my error
first time to see a video of yours but truly, you're amazing.
Thank u very much its very useful!
You're welcome! :D
Can you do a video on concurrent forces please.
