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.
