Any help would be amazing. I've been having trouble with integration for a while. If anyone could show me how to do these instead of just posting the answer would be amazing! Thank you all so much for your time.

1. The integral of (x over c) dx. (c a constant not equaling zero)

2. The integral of (2 over x + x over 2) dx

3. The integral of (x-2x squared + 1 over 3x)dx

4. The integral of (edx)

5. The integral of (3e (exponent) -2x) dx
