Question 923776: Composite trig function problem?
Let f(x) = 4x/(√(1-x^2)) and g(t) = sin t for 0 < t < π/2
simplify so that there are no radicals in the function. Write your answer in terms of sin(t) and cos(t).
(f º g)(t) =
Thank you

(f º g)(t) is the same as
which means t is in quadrant I
----------------------------------------------------------------------
Start with f(x)
Replace every x with g(t)
Replace every g(t) on the right side with
Use a trig identity
Take the square root. t is in quadrant I, so is positive.
