Not really sure how to go about this one...
Suppose X is a uniform random variable on the interval (0, π/2). Compute the density of Y=sinX.
First compute the density of X. Since X is uniform, f(x) = constant for x ∈ (0,n⁄2) (and 0 elsewhere). And
Thus the density of Y = g(X) = sin(X) is (using the chain rule)
