Web10.5. =. 0.79. To graph the sine function, we mark the angle along the horizontal x axis, and for each angle, we put the sine of that angle on the vertical y-axis. The result, as seen above, is a smooth curve that varies from +1 to -1. Curves that follow this shape are called 'sinusoidal' after the name of the sine function. 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 \(2 \pi\). citi manager helpline https://highpointautosalesnj.com
