Anyway to calculate the amplitude and period of a sine wave not using pie? I mean for example I make a sine wave, we will say the amplitude is 3 and the period is 5. Not amplitude 3 and period pie.
y=3 sin(2*pi/5 x)
Has ammtlitute 3 and peroid 2*pi/(2*pi/5)=5
But if you are asking to express it as,
A sin(B x)
Where B is whole or rational and the period is not a multiple of pi then the answer is no since pi is irrational.
