11. The voltage of the power supply in an AC-DEC coupled circuit is given by the function, V(t)=130sin2t+18, where t is the time, in seconds, and V is the voltage, in volts, at time t.

11.a- Find the maximum and minimum voltages and the times at which they occur.[13]

11.b-Determine the period, T, in seconds [1]

11.c -Determine the frequency, f, in hertz [2]

11.d -Determine the amplitude, A, in volts, for this signal [2]

from q1 to 10 I just want the final answer for Q11-a,b,c,d I want every step you go through especially 11a worth 13 marks i want how u find max and minimum step by step, what derivative you used step by step everything, please. i want diagrams full formulas and everything explain very well please
