current and voltage expressions of capacitor and inductor

(See attached file for full problem description)

Problem 2.  Current through 1uF capacitor is given as i(t) = 4 cos (wt) where w corresponds to the frequency of 1 MHz. What is the expression for the voltage on the capacitor?

Problem 3. The same current  i(t) = 4 cos (wt), at the frequency of 1 MHz, is flowing through 1nH inductor. What is the expression for the voltage across the inductor?
