You're expected know (or be able to derive) that the slope formula is:Find the slope of the tangent to
. . . . . .
Substitute into : .
So dy/dx is dy/d theta / dx/d theta and x=rcos theta, y=rsin theta and i found the derivatives of each which gave me:
I'm kinda stumped here. I have dy/dx as a big mess but I don't know what to do from here.
