What have you tried? Which problems in particular are giving you trouble?

[trail jewel]

For 1 js find the intercepts and integrate

For 2 js integrate it normally with A as a constant and substitute infinity for t until the end

3 js read the problem

4 differentiate as if all other variables are constants except t

5 a stationary point is when the derivative equals 0

Irrespective of whether you find their tips useful (I think most of them are) if you want to understand why you're getting it wrong it would be helpful to know what you tried.
