Can anyone solve this??? i am so lost!

Question 1State the amplitude (A) the period (T) and the frequency (F) for the periodic function - 120sin(100 pi

a)t)V.

b)Through how many degrees does a wheel rotate in 10 ms if its angular velocity is 8 rad/s.

c)Sketch one cycle of the given function showing the values of each variable where the curve crosses the axis. V=50sin(4.2*10^2t)
