Thank you for the videos, they are so good. On the internet nobody gives a concept+problems in some websites they only tell the concept and in some other videos they will only solve the problems but here i am getting the both.
I too find other SAT Math channels can be too fast paced and gloss over key concepts. I am glad you found my videos helpful! Best of luck Nadendla!
@@Tutorllini Thank you .Could you please produce a video regarding English for Digital Sat?
@@nadendlahitesh3315 No sorry!

@@Tutorllini The problem below is non- bluebook version. I need help with this problem. A small business owner budgets $2,200 to purchase
candles. The owner must purchase a minimum of
200 candles to maintain the discounted pricing. If the
owner pays $4.90 per candle to purchase small
candles and $11.60 per candle to purchase large
candles, what is the maximum number of large
candles the owner can purchase to stay within the
budget and maintain the discounted pricing?
I can totally feel why you enjoy using desmos so much because there is not such thing in my country either. Being able to graph a function is a HUGE advantage.
Glad to hear Payam! If you haven't already you MUST check out the Desmos Art. See this link:

It is truly amazing how expressive someone can be using math!
Thank you for your videos. your videos are unique, and they are different than all the other videos on the internet.
Thank you so much James!
Thank you for all ur videos! U are a great teacher, im a big fan! I watch all of ur videos and honesty my math had never been better
Thanks for your kind words friend! Good luck with your studies!
Well done dear !
thanks

will all what i note and highlight in the test be deleted automatically?
I don't understand what u did after finding out the tangent of k .Can we not use desmos on the test?
You can use Desmos! I am not sure it is super helpful with this question as there are a lot of steps.
What don't you understand? I am not sure I will be able to explain it any better here.
Hey I know I might be late but for question 9 (29:11) they actually replaced it with this one:
A circle has a circumference of 31π centimeters. What is the diameter, in centimeters, of the circle?
How do I solve this one?
Hey thanks for the tip! I'll check the website every so often to see what they changed 🙄
You just use the formula for Circumference which is on the reference sheet.
@@TutorlliniI forgot about the reference sheet lol. Anyhow, thanks again mate
@@Dakosx You're welcome! Keep me updated on your progress when I post in the Community Tab!

The formula to calculate the circumference of a circle is given by:
Circumference = 2π × Radius
Given that the circumference of the circle is 31π centimeters, we can set up the equation:
31π = 2π × Radius
To solve for the diameter (D), we can divide both sides of the equation by π:
31 = 2 x Radius (2r=Diameter)
Diameter = 31
So, the diameter of the circle is 31 centimeters.
@@aliijaz4995 thanks mate. I appreciate the help
Good fucking video man, ty
You're very welcome! Thanks for watching :)
Hey man, I have a pretty specific question. I'm solving a question very similar to the question you solved last. I have solved it but I don't know why it's making 2 parallel lines when I write the equation of a circle. Can you help me find what I'm doing wrong?
Sure! Follow the instructions in this video to share your Desmos graph:

@@Tutorllini Hey! My comment keeps getting deleted. Could it be due to the reason it has a link? Let me know how I can get it to you any other way.
Thanks!
@@yeet3385 Yeah this sucks. My CZcams links are enabled. However, YT algorithm is blocking Desmos in the same way it blocks links from other social media competitors. Only thing I can think of is you can encode it and copy paste the gibberish:
simplycalc.com/base16-encode.php
Go here and put your link in "text" then copy paste the "result" in a comment. I chose base 16 for 1600 which is the score I hope you get :)
@@Tutorllini Thank you for your best wishes man, I greatly appreciate it. I'm learning from the best, so *wink wink* .
Also man that's a pretty smart way haha, here's the encoded text: 68747470733A2F2F7777772E6465736D6F732E636F6D2F63616C63756C61746F722F396C7666697934367864
but a simpler way could be to just tell you the custom set of numbers and alphabets in my desmos link, so here's that as well: 9lvfiy46xd
Thanks! :)
@@yeet3385 I fixed some stuff for you - the code is a good idea (I should make a video on that...) great idea.
I am making a video on this question very soon... try to be patient.
Here is the fixed graph with some suggestions. You want to make better use of colors, labels, notes, equation of a circle, and function notation.

Could you please do A video on Advance Geometry and Co-ordinate Geometry.
I could solve them in 9th and 10th but I forgot where should i begin from.
There is practically no coordinate geometry on the SAT. I will make more videos as soon as I can!
