∫sin2(x)cos(x)dx (Use C as the arbitrary constant.) U-Substitution:One of the many different integration methods is u-substitution. As its name suggests, it employs the variable u as a transient substitute. An appropriate substitution could possibly convert ...
Set u = 2x and du = 2dx to perform u substitution on the integral. Since dx = du/2, the result is 1/4 times the integral of (1 – cos(u)) du. Step 3 Integrate the equation. Since the integral of 1du is u, and the integral of cos(u) du is sin(u), the result is 1/...
