## Homework Statement

A pendulum's angle is given by (.10 rad)cos(5t + pi)

where t is in sec. What is the initial angle?

## Homework Equations

## The Attempt at a Solution

Do I plug in t= 0 to get this angle, or is the phase constant this angle? I read that the phase constant specifies initial conditions, but I'm not entirely clear on what it means.
