Simple Question About Pendulum I Can't Do !!
The motion of the bob of a pendulum is described by
theta = 3cos(3t) - sqrt3 sin(3t)
where theta is the angle of the bob from the vertical. What is the amplitude of this motion??
as an attempt, as i know what the answer is, but just dont know how to get to it i substituted the answer for theta and tried to find what t was
but it didnt help i dont really no where to start for this probelm
thanks if youcould help
