The tangent to a point P (p, pi/2) on the curve x=(4y-sin2y)^2 hits the y axis at point A, find the coordinates of this point.

p=4pi2 differentiating with respect to y we have dx/dy = 2(4y-sin2y)(4-2cos2y) substituting in the value of y =pi/2 we have dx/dy = 24pi, which means dy/dx =1/pi24using (y-y_1)=m(x-x_1) we have...

The parametric equations of a curve are: x = cos2θ y = sinθcosθ. Find the cartesian form of the equation.

x = cos2θ  y = sinθcosθcos2θ = cos2 θ  - sin2θ cos2 θ  + sin2θ  = 12cos2 θ  = 1 + cos2θ cos2 θ  = 1/2(1 + x)2sin2θ  = 1 - cos...
