# Inverting amplifier and sinunsoidal math

## Homework Statement

I have an inverting amplifier with v(in)=0.001sin(2000πt) and v(out)=-5sin(2000πt + 25)

## Homework Equations

what is the input amplitude and at what degree?
what is the output amplitude and at what degree?
what is the voltage gain and at what degree?

## The Attempt at a Solution

I am not really sure about a solution because my sinusoidal math are not very good ,so if anyone can help please do.
Also i searched google about sinusoidal math and i can't really find something that can help me solve this exersice,so i would apprisiate it if you also post some links that can help.

The general form of the function that fits your problem is:

$$v(t) = A sin(\omega t + \phi)$$
