  • calculus -

    ok, if f(u) exists, and u=G(x)
    then

    y= f(u)
    dy/dx= d(f(u)/du * du/dx

    but u=G(x)
    so du/dx= G'

    Now in practice.
    r= sqrt(Theta*sinTheta)

    dr/dtheta= 1/2 (1/sqrt(Theta*sinTheta))* d(theta*sinTheta)/dtheta
    and d(theta*sinTheta)/dtheta= sinTheta+ theta*cosTheta.
