How to Convert From Polar Coordinates to Rectangular Coordinates (Precalculus - Trigonometry 37)

How to use trigonometric relationships to change Polar Coordinate represented points into Rectangular Coordinate represented points

Professor Leonard, thank you for another outstanding video/lecture on How to Convert From Polar Coordinates to Rectangular Coordinates in Precalculus/Trigonometry. This is an important topic in Mathematics and Applied Engineering. This material is simple to understand but finding the quadrants for each problem can be confusing.

Thanks you are the best.. when I graduate and become an engineer.. 20% of my first salary is going to you sirr🌹

Thanks so much Professor Leonard, YOU ARE THE

You taught the earlier stuff so well that I was already using polar coordinates in some experiments with computer graphics without even knowing it.

On the last example: (-4.98, -3.85)??? Am I missing something? I'm getting (-4.74, -3.67). If someone would be able to advise, please, that would be much appreciated. Thank you so much!

Sir i am gona watch all your video in my 3 year college life for sure. Finally my search come to end on you.
Thanks alot sir.
❤❤❤❤

can we just use cos inverse to get the angle if we find r prior to that ? specially if the angle is in quad 2 where tan inverse doesnt return any angle of that while cos inverse does.

Каждый 1 благодарите? Нам не дочитать до строк? "Мы стремимся к экспоненте" эта фраза меня не покидает. Const?

My math tacher teach us polar coordinates in 30 mins with no one understanding

Just found your Youtube yesterday and, having just entered college after dropping out of HS years ago, your videos are such an awesome refresher! THANK YOU

[vishalmittal]

Sir please upload videos regarding discrete mathematics including how to write proofs

[newjsdavid]

thank you for explaining this stuff thoroughly
