the equation is

x(t) = A cos (wt + f)

v(t) = -A w sin (wt + f)

f is phase constant, w = angular velocity

i know if i double A and T, the first part of the v(t) equation will be like:

-2A * 2pi/2T = -A * w, not changed, but what about that part in the sine ?

the question ask if it is halved, quadrupled, unchanged, or doubled
