`(3 cos theta + cos 3 theta )/( 3 sin theta - sin 3 theta ) = `

Show that the equations of the normal at any point theta on the curve x = 3 cos theta - cos^3 theta, y = 3 sin theta - sin ^3 theta is 4(y cos^3 theta - x sin^3 theta) = 3 sin 4 theta

Find dy/dx if : x= 3 cos theta - 2 cos^3 theta , y= 3 sin theta - 2 sin^3 theta

If x = 3 cos theta - 2 cos^3 theta,y = 3 sin theta - 2 sin^3 theta , then dy/dx is

The normal to the curve x= 3 cos theta - cos^(3) theta , y=3 sin theta - sin^(3) theta at theta = (pi)/(4) -

Find the equation of the normal to the curve given by x = 3 cos theta - cos^3theta y = 3 sin theta - sin^3 theta

(3cos theta+cos3 theta)/(3sin theta-sin3 theta)=

( cos 3 theta - sin 3 theta )/( cos theta+ sin theta ) =
