Best ResponseYou've already chosen the best response.1x = r*cos(theta) x = sin(4theta) * cos(theta) ... replace 'r' with 'sin(4theta)' what do you get when you derive both sides with respect to theta?

Best ResponseYou've already chosen the best response.1if the theta's are throwing you off, then think of them as x ie think of it as y = sin(4x)*cos(x) what is dy/dx here?
