Scaling, stretching and shifting sinusoids
This is a brief and simple [1] explanation of how to adjust the
standard sinusoid sin(x) to change its amplitude, frequency and
phase shift. More precisely, given the general function:
[s(x)=A\cdot sin(w\cdot x+\theta)]We’ll see how adjusting the parameters , and
affect the …
