After much fiddling, I derived a relation between the angle of attack and time. https://farm8.staticflickr.com/7500/...fd5e3dc417.jpg a,b,c,d, and e are constants. Can anyone convert this into an elemenatry function, theta(time)?

Your equation isn't valid for $t = 0$ because the right hand side is zero, but the left hand side can never be zero.

That's fine, I can use it as a piecewise function, theta(t)=theta intial for t=0 and theta(t)=given left hand side for 0<t<pi/2

In answer to your question: it can be expressed as a function of t, but it's messy.

well, yeah, I gathered as much. But what is that function.
