AP Calculus BC -- Improper Integrals

Question

1. ∫ of e^1/2 dy from infinity to 0.
2. ∫ of dx/x-1 from 3 to 0.

Number 1 is apparently that way, not sure if there are no typos.

Answer 1

Integral of dx/(x-1) diverges. It has no solution.

Integral of e^1/2 dy = ye^1/2 + C

e^1/2 is a number, a constant. It's treated like any other constant in an integral.

For example, integral 1dx = x + C
