WebFeb 13, 2024 · Earlier, you were asked how an equation changes when a sine or cosine graph is stretched by a factor of 3 . If a sine graph is horizontally stretched by a factor of 3 then the general equation has \(b=\frac{1}{3}\). This is because \(b\) is the frequency and counts the number (or fraction) of a period that fits in a normal period of \(2 \pi\).
