You don't say where the problems lie, so I'll just give you some general hints.

1

Try, say, as a first approximation, and then use

to get the second and third approximations.

2 Use the substitution . Very straightforward.

3 Image too small to read fully, but it looks as though you need to expand to get , and then sum these two terms separately.

Please explain what you've tried and where you get stuck.
