Heya can you please help me with some C3 diff. :smile:

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 :redface:

Answer ---

Spoiler



Thank you :smile:

EDIT - Neverrrrmindddddd I was being silly :biggrin:

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.

You have got to be kidding me...why didn't I think of that :frown:
