## Homework Statement

The angle of a pendulum is θ(t)=(0.270rad)cos(4.00t+1.00π), where t is in seconds.

Determine the initial angular velocity.

## Homework Equations

ω=2πf

## The Attempt at a Solution

[/B]

I solved for the frequency, which was 6.37E-1 Hz and subbed it into the formula above and got 4rad/s which is the same ω in the equation but it is wrong. Am I missing something because I can't figure out what is wrong with my method.
