PreCalculus - Polar Coordinates (10 of 35) Graphing Polar Equations: r=cos[2(theta)], Four Leaf Rose

In this video I will graph polar equation r=cos[2(theta)], 4 leaf rose.

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

Siti
cos (2pi/3)= cos (120 degrees) = - 1/2 you are correct.
(I made an error)

[skyora]

excuse me sir, why when cos (2pi/3), the r is - sqrt2/2? isnt it -1/2..?
thank you, btw you help me a lot!! :)

Can i ask something? Why this started from pi/6? Please answer my question😊 Thank you so much sir

Hi, i have exam weekend and polar coordinates will be the topic.Generally, the intersection area calculation is the question. But i have limited time, which way should choose for graphing the polar coordinates like limocan, heart or etc.Best regards<3

Helpful thank you.could you make a video to make out this problem the area bounded by :(x/5)^2+(y/4)^(2/3)=1

[fundacan]

yayy finally I got it! Thanks to you it was very helpful yo all the way to Turkey

THANK YOU MOTHER YOU ALWAYS TAKE CARE OF MY BODY, WHEN MY FATHER DONE BITTING ME FOR MULTIPLICATION

Way easier than when my professor explains it
