Find the angular velocity of the system after 12 seconds

The angular acceleration of a system is described by the following equation: a(t)=d^2Radians/dt^2=10cos (5t). 
Find the angular velocity of the system in radians after 14 seconds

In order to solve this problem completely, you need to also state 2 initial conditions, such as θ(0) and ω(0).  Without them, there will be 2 undetermined constants in the solution.

a(t)=d2θ/dt2=10cos(5t)

By the way, the correct units for angular velocity are radians/second, not just radians.
