Homework Help: Calculus

Posted by Jessica on Thursday, October 13, 2011 at 9:27pm.

Find the equation (in terms of x and y) of the tangent line to the curve r=3sin3(theta) at theta=pi/4.

I dont know if I'm taking the right approach for this question but her goes what I did:

I found the slope

I got (9(-1/2)(sqrt3/2)+3(sqrt3/2)(1/2))/(9(-1/2)(1/2)-3(sqrt3/2)(sqrt3/2))

Is that right? what else do I have to do?
