Question

I need to turn this in to rectangular equation r=4sin(3ø)

Answer 1

Multiply both side of your equation by r

Answer 2

then you have to recall and use these relationships:

r^2=x^2+y^2 and y=rsin(theta)

Answer 3

How will multiplying by r help?

Answer 4

you should get r^2=4rsin(3theta)

Answer 5

Yes, but I am looking to have x and y and no r and theta
