5. Let a, b, k, and n represent constants. Rely on the knowledge of derivatives to solve each integral below in one or two steps. (Be careful with the first one. There's a catch!) 1 a) x" dx d) dx g) ekx dx V1- x2 1 b) a* dx f(x) e) dx h ) dx 1+x2 f (x) 1 c) f: dx f) dx X xvx- - 1 6. These improper integrals have finite limits of integration, but between these boundaries the function has a discontinuity. 1 1 a) dx b) x - 2 (x - 1)2/3 x
