Compute r [0,π/2] f dµ, where f(x) = ( sin3 (x), if sin(x) is rational; cos5 (x), if sin(x) is irrational.

Monica build a remote control toy airplane for science project to test the plane she launched it from the top of a building the plane travel a horizontal distance of 50 feet before landing on the ground a quadratic function which models the height of the plane in feet relative to the ground at a horizontal distance of x feet from the building is shown
