(C) Use (17); rewrite as .
(B) Rewrite as . Use (3).
Compare the integrands in Questions 14 and 15, noting the difference.
(A) Divide to obtain . Use (2), (3), and (4). Remember that
k dx = kx + C whenever k ≠ 0.
(E).
(Note the Binomial Theorem with n = 3 to expand (x − 2)^3 .)
(D) The integral is equivalent to dt. Integrate term by term.
(A) Integrate term by term.
(D) Division yields
.
(E) Use formula (4) with . Then . Note that the
integral can be written as .
