1. ## can someone walk me through this

need help.....

The value of current, i amp, at t seconds is

i= 15 sin (100 pi t + 0.6)

Find
the amplitude
the period
the frequency
the initial phase angle when t =0 expressed in both radians and degrees
the value of i when t=2.5
the time in milliseconds when the current first reaches its maximum value

I need all the help I can get thanks
