Heres where Im struggling, I cant seem to change equations from rectangular to polar and vice versa(adsbygoogle = window.adsbygoogle || []).push({});

an example

x^2+y^2-2ax=0

heres what I got when I tried

r=2a cos theta

and thats a graph of a rose curve, I think, Im about 10% sure on that answer

heres an example of one I have no clue on

(x^2+y^2)(arctan(y/x))^2=a^2

heres what im thinkin on this one

the x^2+y^2 can = r^2 and the arctan (y/x) can = theta

so you would have (r^2)(theta^2)=a^2

I dont know, I just cant get this
