write the expression as an algebraic expression in x.
tan(sin^-1(x))
-----
Tangent of the angle whose sin = x
------
By definition sin = opp/hyp; so opp = x and hyp = 1.
The adj = sqrt[x^2 + 1]
-------
Ans: Tan = opp/adj = x/sqrt[x^2+1]

-----
Tangent of the angle whose sin = x

By definition sin = opp/hyp; so opp = x and hyp = 1.
The adj = sqrt(1-x^2)
-------
Ans: Tan = opp/adj = x/sqrt(1-x^2)
