Question

using the implicit differentiation how would you solve this? yx^3-cosxsiny=7x I dont get it!

Answer 1

y(prime)=(3/7)*yx^2

Answer 2

Think of y as a function of x. So think: y(x)*x^3-cosx*sin(y(x))=7x.
So the y(x) forces you do do chain rule when you differentiate, right.
Remember to use the product rule, too
