The question is:

tan(arcsinx)=

I know that inverse of sin is 1/sqrt(1-x^2) however this question still confuses me. The outcome is x/sqrt(1-x^2), how did the tan create the additional x ?

oops i think i meant to say that the derivative is 1/sqrt(1-x^2) dang I am tired.
so basically what i said in the original question is irrelevant.
