Finding equations of sine and cosine curves

Interactive practice questions

Determine the equation of the graphed function given that it is of the form $y=a\sin x$y=asinx or $y=a\cos x$y=acosx, where $x$x is in degrees.

A Cartesian plane is depicted, with the x-axis ranging from 0 to 360, labeled at intervals of 90, and the y-axis ranging from -3 to 3, labeled at intervals of 1. A sinusoidal wave passing through (0,2) is plotted on the plane with peaks at 2 and -2. The cycle ends every 360, however this is not explicitly labeled.
