Integration: f cont & ∫(5 to 0 ) f(x)dx = 11 then ∫(pi/2 to 0) f(5sint)cost dt = ?

Integration: f cont & ∫(5 to 0 ) f(x)dx = 11 then ∫(pi/2 to 0) f(5sint)cost dt = ?

If the function f is continuous and ∫(5 to 0 ) f(x)dx = 11 the ∫(pi/2 to 0) f(5sint)cost dt =

So far I have x=5sint

x = 5 sin(t) → dx = ?
