(1.)
I have a "particle in motion" problem that is asking me when a particle is at rest, which I understand to be when velocity = v(t) = 0, so
v(t) = - (π/4) sin (πt/4) = 0.
The given answer is as follows:
- (π/4) sin (πt/4) = 0
sin (πt/4) = 0
πt/4 = πn.
t = 0,4,8 seconds.
(2.) Can someone please explain to me how 0 becomes πn, and/or what specific mathematical concept(s) I need to review?
