Question:
There are several ways to express the indefinite integral of sech x.
a. Show that ∫ sech x dx = tan-1 (sinh x) + C (Theorem 6.9).
Writeand then make a change of variables.
b. Show that ∫ sech x dx = sin-1 (tanh x) + C. Show that and then make a change of variables.
c. Verify that ∫ sech x dx = 2 tan-1 ex + C by proving d/dx (2 tan-1 ex) = sech x.
