Tutorial Exercise Evaluate the integral Step 1 Since S 15 sin x cos x dx has an odd power of of cos x we will convert all but one power to sines We know that 15 sin x cos x dx cos x 1 11 sin x Step 2 Making this substitution using 1 15 sin x cos x dx gives us Step 3 Submit 15 15 sin x 1 sin x cos x dx 1 Skip you cannot come back 1 15 sin x cos x dx Since cos x is the derivative of sin x then 1 15 sin x cos x dx can be done by substituting u 15 sin x cos x 15 sin r cos r and du dx dx
