(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

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

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

2. Relevant equations

3. 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.
