- This precalculus video tutorial explains how to convert polar equations to rectangular equations. It contains plenty of examples and practice problems. In polar form, the equation contains the variables r and theta which is the radius and the angle of the vector. In rectangular form, coordinates are represented by x and y.

Your good bro
For real
Fr
I like how this shit is way more effective than my prof yapping for an hour
It sucks that after every Trigonometry class session I have to come home and watch videos to actually learn the material; but, you, my friend, explain math very well. So well that I understand the material immediately. Thank you for your videos!
James Stup AGREED😭😭😭😭😭❤️❤️❤️❤️❤️ THIS GUY IS REAL MVP
Sir you are always pronounce instead if cos© (cosin©) 🤔🤔
English isn't my first language, and i could understand as well.
This is the greatest math tutor i have ever known.Thanks to him i can easily relate with what the lecturer taught in class.
feel u bro
OH MY GOODNESS, The Organic Chemistry Tutor!! You are AMAZING! Who on earth is that masked man!! You have helped me so much through trig - precalc - calc I and calc II
Thank you! Thank you! Thank you to the 100 Thousandth Power!!
Why not one millionth power?
He’s a mexican dude
@@joshmayes1538 I like that even better👍
@@joshmayes1538 Nah, 10 to the googol power!
Why are you here then
Watching this on 2 times speed right before my precalc quiz 💀
Me too bro
I️ was struggling with a trig unit in precalc and couldn’t get much help from my teacher and your videos totally helped me through it- thank you! Because of two of your videos I️ aced the test with a 98!
We've been going over this for the past week and a half in my precal class and I haven't been able to understand anything until now thanks to this video !!! THANK YOU!
For real, my professor only knows how to solve problems for himself, he doesn't know what means teaching
BRUHHH MY LECTURER LITERALLY BE TALKING TO HERSELF
Thank you! This is the best explanation of polar equations yet that I've encountered.
You are amazing! You've explained this crystal clear! Thank you thank you thank you
Wow helping me not only with chem and physics, but precalc too
Thank you so much for saving my butt on my exam tomorrow! This is great!
bro u r awesome .. the best scientific channel i've ever watched 👏👏.. keep it up.
Best video out there! Better than the speaker on khan academy!
yes!! so much better
Facts
Don't compare people though or say someone is better than another, many people prefer him, i like both of them, you can say instead "I can understand you better"
i loooove your channel, thanks for everything!
killed it! writing an exam in two days and I feel good about polar equations now.
I literally love you, you are so amazing. Thank you for your videos, they helped more than the lecture
I love you, you've saved me from so much homeworks!
You are the GOAT for both my Chem and Trig classes! Thank you yet again good sir.
you help and explain things better than my math teacher thank you.
This video saved my grade! THANK YOU!
Professor Organic Chemistry Tutor, thank you for showing How to convert Polar Equations to Rectangular Equations and vice versa in Calculus Two. All Calculus Two students should be familiar with this material from Precalculus Mathematics and Trigonometry. This is an error free video/lecture on CZcams TV with the Organic Chemistry Tutor.
this one was actually so fun to do along with the video.
yes, i love the videos they help me so much with math
This helped a lot sir! thank you
Final trig exam in 2.5 hours. Wasn’t totally feeling I grasped it yet. Thank you!
Did you get an A?
Thank you, as always.
you are a lifesaver. thank you so much
This is wonderful ❤❤❤❤
Please upload a video explaining partial derivatives for calculus. Thank you!!
i starting learning from u since highschool didnt think i would use u for university though still using u in univetsity
you are the greatest
Your voice pierces through my earwax.
Dumbass: “ya heard of Q tips?”
2:11 I love how this dude always says "UNPAUSE the video" instead of saying "continue the video or play the video"
Watch the ads guys, he deserves it.
Thanks homie
bro this dude is the goat
thank you!!! i was even able to find quicker ways of solving them half way through
you are my hero 💗
very nice thanks a lot
YOU ARE A HERO
damn it, I studied for the test but forgot to go over these polar coordinates, surprisingly the majority of the test was these even though we just went over polar coordinates the day before. thx you good sir for the help, i probably rushed but thx to you i did pass with an average.
🙏👌👌👌Beautiful explanation 😊😊☺️☺️
you're the bomb dude
thanks a lot!!!
Very helpful
thanks!
Thanks sir 🙌
Thank you till ♾❤️..
13:02 Why R^2 [sinx*cosx] = RsinxRcox instead R^2sinxR^2cosx? Help!
this vid explained it so much better than my trig professor ;-;
Wouldnt the R^2 ( sin0 cos0) = sinr^20 cosr^20 and not rsin0 rcos0
have a test tmr and the notes didn't really help, thanks
Thanks gang
the problem around 15:00 can also done by dividing R by sin^2
R sin^2 = 5 cos
multiply both sides by R
R^2 sin^2 = R 5cos
Rsin * Rsin = R5cos
y^2 = x
Steve mamo its 5x instead of x .. but yeah i think it can work that way also 👏 .. good job 👌👍
That’s the way I thought of too
Me too I was like WHHYYYYY
yeah ,gotchu ...well done !!
Thanks
thank you
Holy shit super helpful
thanks
goated fr fr
8:26 can we multiply both sides by sin?
Learning this before I go to class today so I can feel smart ;D
Why for the last problem did they multiply by r^3?
its been awhile .. IM SURE I WILL BE OK AND MAKE IT BACK TO ALL THIS AGAIN
Nice
At 9:13 couldn't you just divide by sintheta and then swap it for csc and have 1/y=3 so y=1/3?
Why have you multiplied R^3 in last problem?? help me i don't understand
Saved my ass for polar test. big thanks
You could you x/y and cotangent for pi/2
How do I deal with this problem
3(cos 135 + isin 135)
The goat 🐐
how to find rectangular coordinates in polar equations
one of the only reasons i’ve been improving on math is bc of this channel lmao
How is 'tan(pi/4)' equal to 1 because when I type it in calculator I dnt get 1 but instead 0.01370864253 please
why does everyone do the easy nice round number in the examples? I'm stuck because I have r^2= 19cos theta.... my answer is (x^2-19x+y^2)r = 0 but is that even right?
You can’t have r in a rectangular equation
Nobody on CZcams makes better videos.
tysm
Pllllzzzz can you do a vid on conversion from spherical to cylindrical equations!!!
just did
At 13:41 can I solve for either x or y? Or do I just solve for y?
You could solve for either. Solve it in the way that the exam question asks you to.
Hello there
Ø 300mm R = 250mm 90 °
Can give 5 pieces of elbow area, excel formula.
thanks
If z=cosθ+isinθ and w=sinα+icosα. Express Z x W in the form p+qi, where p, q∈R. Hence find the maximum value of p^2+q^2
Can you add a video to explain how to solve the 3-5 trick questions that now seem to be a standard part of every test? Or is it as I'm thinking: there's no way in hell to solve a trick question. Thx!
legend
Holy cow. Not sure I ever would’ve come up with multiplying both sides by R cubed 😂😂😂😂😂
i love you
Janet Yang love u too
slayed
Instead i multiplied both sides by r getting r²=5rcosx/sin² then r²=5x/sin ²x then i multiplied both sides by sin ²x r²sin²x=5x then its easy to see that r²sin²x=(rsinx)²=y²
how to find rectangular using polar equations
all hail the one and only OCT
thank you for making this ridiculous shit somewhat easier to swallow
R=5+cos³theta
Please solve
👍👍👍👍👍👍
6:44 (bookmark for self)
Mark Wahlberg is teaching me math
For anyone looking for a recap of this video. He is basically talking about Pythagoreans theorem. Saved you 18 minutes of your life.
❤❤
1st
Why he sound like Lil Tecca???
18:08 YOU SAVAGE
0:42 timestamp so i can have the formulas
