solve with a *HANDWRITTEN* solution

4. Consider the integral 1 = [1 - tanh (a)] ed da, where tanh(@) = In an attempt to study the convergence of I, we consider the two integrals 1 = [1 - tanh'(x)] ed da and 12 = [1 - tanh' (x)] el dx. (a) (4 points) Does /1 converge or diverge? (b) (4 points) Does Iz converge or diverge? (c) (1 point) Does I converge or diverge
