Hey, everyone! We're on our Polar Unit in Pre-Calc and I'm completely lost when it comes to finding simultaneous points of intersections. I understand the method, but I just can't seem to get past step 1 much to my chagrin.
Take for example,
r = 1 - sinθ
r = cos2θ
Now, I set the two equal to each other.
1 - sinθ = cos2θ
And that's about as far as I get despite trying to substitute cos2θ with 1-2sin^2θ.
Any help would be greatly appreciated!
