I think it should be 120 instead of 135... btw Thanks! This really helps!

[@MichelvanBiezen]

Yes, you are correct, it should have been 120 degrees

@@MichelvanBiezen PERFECT, YOU HAVE REALIZED THE MISTAKE

[@Cabismer]

You just saved me . I have an exam tomorrow and was really stuck in drawing polar equations🤝❤️

[@MichelvanBiezen]

All the best on your exam! 🙂

Howcome for the first one -1 puts us positive direction and for the second one -1 puts us in the negative?

[@MichelvanBiezen]

It depends on the angle when r = - 1 and the angle is 180 degrees, the point will be in the positive direction.

You are my hero. Thanks a million

[@usmanhaider295]

Outstanding efforts

[@MichelvanBiezen]

Thank you. 🙂

[@leonedithlozano328]

Thanks a lot Sir!, that was so informative!

[@anamarlenejesus]

cos(135) =-1.4142, but thank you!!!!!, I love your clasess!!!!

[@MichelvanBiezen]

Yes, you are correct.

[@Ahab1086]

Very helpful thanks for posting...cos(135) is not -0.5 though

[@MichelvanBiezen]

Thanks for pointing that out.

[@alexnghilifilwaelias4646]

I was about to comment that, he should have put 120 degrees or lets say (2/3pi)

[@Theclippingkon]

@@MichelvanBiezen my teacher would beat me for this mistake

[@thelonehiker4698]

thanks I am in calc 2 and I we are doing these again

[@Theclippingkon]

how about now?

[@-SiddharthaChappidi]

very nice sir

[@serkangoktas8753]

why dont we draw pi to 2pi

[@MichelvanBiezen]

Try it and see what happens. (you will trace the same path)

[@windrimondo]

How is cos(135) equal -0.5???

[@MichelvanBiezen]

You can find out looking at this playlist: TRIGONOMETRY BASICS - PRECALCULUS 6

[@jonahperry2698]

Great video. Why did you use degrees instead of radians? Lol

[@mamunipalai6150]

Thank u sir.

[@kritikanarula7430]

What does r denote over here? ...is it the distance from the origin?

[@MichelvanBiezen]

Yes, r is the distance from the origin

[@kritikanarula7430]

@@MichelvanBiezen what does distance of -1 denote then?

[@graret4520]

cos135 is not -0.5, sir. It's cos120

[@MichelvanBiezen]

You are correct.

[@melikey.3319]

Actually it’s 150

[@Theclippingkon]

@@melikey.3319 no 120

[@حسينمنذرسعدمنذر]

Love u master

[@MichelvanBiezen]

Thank you. Glad you found our videos. 🙂

[@melikey.3319]

But cos135 is not equal to -0,5
