It IS 0.2? Phew, thank you. I graphed it, too, I see it now. Thanks for your help!

Okay, so I took the derivative and set it equal to zero, and now I have 0=-1.6sin8t and no theta at all, which is what I am solving for. Also, t would equal 90 (or, since it's in radians, pi over 2), and when you sub it back into the original equation, theta is equal to 0.2 radians, which...

Riiiiight, I don't need the absolute, I can just find the local. Thank you very much! xD

Homework Statement A 15-centimeter pendulum moves according to the equation: theta=0.2cos8t where theta is the angular displacement from the vertical in radians and t is the time in seconds. Determine the maximum angular displacement and the rate of change of theta when t=3 seconds...
