Question

How do I relation in amplitude compared to parent function of sine?How do I describe the relation in period compared to parent function of sine?

Answer 1

`\begin{gathered} y1=sin(x) \\ y2=1.5sin(4x) \\ The\text{ amplitud of y2 is 1.5 times of y1} \\ The\text{ period of y2 is 4 times less of y1} \end{gathered}`
