1. ## sin(Asin(f.t))

I have a time varying angle described by alpha=A sin (f.t). From this angle alpha, I want to take the sin(alpha). This results in sin(A sin( f.t)). Does someone know a nicer way to write this down?

What is A?

If it is the amplitude, the angle α cannot be expressed by the given equation.

3. ## A is amplitude

Yes , A is amplitude. So my angle varies from -0.1 to +0.1 RAD in f=1/T seconds.
So alpha(t)=0.1*sin(f*t). In the end I want to calculate q(t) which is sin(alpha(t))

Pitty that this has no nice rewriting.

Thanks anyway !
