What is the indefinite integral of ∫ [sin (π/x)]/ x^2] dx ? This is what I did: Let u = π/x (to get the derivative and du:) π*1/x π(-1/x^2)dx = du π(1/x^2)dx = (-1)du so, 1/x^2 = -1/πdu then ∫ [sin (π/x)]/ x^2] dx = ∫ sin(u...

what is the integral of {sin(x)tan(x)} i tried turning tan(x) into sin(x)/cos(x) then doing u substitutions but i always have an extra sin(x) left. can you help me pleeeease
