    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?

    Thanks in advance.

    What is A?

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

    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 !
