The angle turned through the flywheel of a generator during a time interval t is given by theta = at + bt^3 -ct^4, where a, b, and c are constants. What is the expression for its angular acceleration?

α =

Explanation:

The angle, θ, has been given as:

θ =

To obtain angular acceleration, α, we have to differentiate the angle twice, with respect to time, t.

Differentiating once will yield the angular velocity, ω:

ω = dθ/dt =

This can then be differentiated to obtain angular acceleration:

α =  dω/dt =

i need to show me the graph so i can give u an answer
