PreCalculus - Polar Coordinates (18 of 35) Graphing Polar Equations: r=1+/-cos(theta), Limacons

In this video I will graph polar equation r=1+2cos(theta), r=1-2cos(theta), r=1+2sin(theta), r=1-2sin(theta), limacons.

Next video in the polar coordinates series can be seen at:

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

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

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

[Ahab]

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

[thelonehiker]

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

[anamarlenejesus]

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

[graret]

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

[leonedithlozano]

Thanks a lot Sir!, that was so informative!

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

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