The point p lies on the curve with eqn x = (4y - sin(2y)^2, given that p has coordinates (p,π/2), p is a constant, a) find the exact value of p; the tangent to the curve at P cuts the y-axis at A, b) use calculus to find the coordinates of A.

a) Sub y= π/2 into equation, hence x coordinate is 4π^2 b) to find equation of the tangent, differentiate the equation using the chain rule (wrt y) and then substitute the coordinates of p into the different...
