A fan blade rotates with angular velocity given by omega_z(t) = gamma - Beta(t)^2 .


Calculate the angular acceleration as a function of time.


I don't even know where to begin and my book is all but useless. Any ideas?

Are you serious?

Here's one idea: differentiate!
 
Well, if this was velocity and accelaration you could think of velocity as dv/dt and acceleration by d²v/dt², from this we could clearly go from one to the other...
 
Hey I'm sorry I'm not a physics genius like you are cepheid. I appreciate the help but I can do without the snide comments. Anyway, I was leaning toward differentiating and I tried it and came out with a wrong answer. Computations were probably inaccurate though.

Thanks, my calculus is a bit rusty and I integrated instead of differentiated...
