7) intleft(sec left(frac{x}{3}right) tan left(frac{x}{3}right)right) d x

Question

Accepted Answer

Step:1 ：Substitute u = (frac{x}{3}), then du/dx = (frac{1}{3}), and dx = 3duStep:2 ：Integrate with respect to u: (3int(sec(u)tan(u))du = 3sec(u) + C)Step:3 ：Substitute back (frac{x}{3}) for u: (3secleft(frac{x}{3}right) + C)Step:4 ：boxed{3secleft(frac{x}{3}right) + C}
