Question

Could anyone help me find this derivative?

Answer 1

as this is a quotient, it is intuitive to use the quotient rule.

Answer 2

h'(x) = ((tan(3x))'*x^2 - tan(3x)*(x^2)')/(x^2)^2

Answer 3

I got this
(3 x^2 sec(2)-2 tan(3 x))/x^3

Answer 4

what is the derivative of tan(x)?

Answer 5

sec^2x?

Answer 6

yes, so you need to fix that.
