The Sinister Sine Function
Hello,
I have to complete an assignment with the help of Ti-Interactive (which I'm not very good at using!)
I know that the general formula for the Sine Function is
f(x) = a*sin(bx+c)+d

A = amplitude
D = baseline
C = movement along y-axis

But what does B stand for? And how can I find it?

Thanks,
Amine :)

It's related to the period of the function.

If you're working in degrees, period $= \frac{360}{b}$.

If you're working in radians, period $= \frac{2 \pi}{b}$.
