I don’t understand this question -
“Find the sinusoid magnitude and phase “in degrees” at 0.5ms for this
V(t)= 5 sin (2π * 500 t + π/4 ) [V]
π= Pi;
Thanks

the equation represents a sinusoidal shaped voltage waveform. the maximum amplitude of the voltage waveform is 5.
You need to find out the amplitude and phase when t=0.5ms.
Hint: replace t with given value for amplitude and phase is obvious from the equation.

You mean i do this
V(.0005)= 5 sin (2pi * 500 (.0005) + pi/4 ) [V]
Is this what you mean?
Thanks ;

yes amy.
calculate the values, inside is phase and take sine of it and its magnitude
