Pardon the handwriting
A) You can use substitution method to get the answer. Try working backwards to confirm the answer.
B) Similar to part (a). Practice these sort of questions and youll get the hang of substitution in no time.
C) Use trigo identity to simplify and then integrate as follows.
D) As the question says, you can use the derivative of cot(x) to subsequently solve the integral of csc^2(x). Since tan(pi/2) = infinity, it can be said that cot(pi/2) = 0
Hope it helps!
