Question

How do you determine the phase shift of a sine function?

Answer 1

My teacher said, in his video, that it's just the first point on the graph, but I don't understand that. I want to understand phase shift fully.

Answer 2

\(\bf y=sin(x)\qquad \qquad

y=Asin({\color{red} B}x+{\color{blue} C})+D\qquad \textit{phase shfit}=\cfrac{{\color{blue} C}}{{\color{red} B}}\)
