(d) \int \frac{1}{e^x + e^{-x}} dx
Calc 2, Fall 2022
Problem Set 1
(e) \int \sqrt{\frac{1 - x}{1 + x}} dx
(f) \int \frac{xe^{kx}}{(1 + kx^2)^2} dx where k is a constant. If there are any particular values of k where your
method doesn't work, compute those antiderivatives separately.
(g) \int_0^1 e^{\sqrt{x}} dx
