I'm not sure how to sort out the following:

1. integrationOf (3 + sqrtOf(2x + 5))

Answer: ?

2. integrationOf( e^7x-4) dx

limits 1 to 3

Answer: (e^7x-4/7)

limits 1 to 3

3. integrationOf((5-3x)^-1) dx

limits 0 to 1

Answer: ?

p.s. what are the tags to use to draw the actual characters? any docs around here?
