hi guys,(adsbygoogle = window.adsbygoogle || []).push({});

im a little stuck at the moment trying to answer the follwing calculus question, can anyone help me please.

if x=a(theta-sintheta), y=a(theta+sintheta), find dy/dx and d^2y/dx^2 at the point where theta=pi/2.

and given that dy.dx=(dx/dy)^-1, find a fomula for d^2x/dy^2 in terms of dy/dx and d^2y/dx^2.

and verify the formula for y=x^2

i really dont know where to start with this one. :uhh:
