    Heya can you please help me with some C3 diff.

    find dy/dx in terms of y when

    x = 5sin3y

    i've rearranged to make y the subject...

    so y = 1/3sin^-1(x/5)

    then i've differentiated and subbed x back in but i'm not getting the right answer

    Answer ---

    Would you not just do dx/dy then do 1/dx/dy?

    dy/dx=1/dx/dy. Using this rule just differentiate 5sin3y with respects to y and divide 1 by that answer.
