Question

Philoid · Accepted Answer

To draw the graph of the curve sin(x/2) assume some standard angle measures which will help in locating the points and drawing the curve.

X				π
sin(x/2)				1		0

Therefore, the graph of curve 2cos(3x) can be drawn as

Here, the frequency of the function sin(x) is decreased by 0.5 times.
