if y=x^TAN(x)
is y'=TAN(x)·x^(TAN(x) - 1)·(SEC(x))^2
i got the answer by using the chain rule & the power rule by letting u=TAN(X) and y=x^u. not sure if that's the right answer since when i graph the function of y and y' , they don't show any relation with each other.
i think i have to use the chain rule twice if i want to use the power rule, since x^u does not equal to ux^(u-1) (i think, not exactly sure).
can someone please help me out, thanx.
