What are the probabilities of finding the electron anywhere between x=0 and x=L/4? (n=1 and n=2) Can you give example to me?

i don't know how to perform the differentiation. because i have not study differentiation, i don't know question 2 too.

Sorry, i don't know the policy of this forum. Anybody can help me?
