Question

What are sinusoidal graphs?

Answer 1

A graph which follows the sine ( or is derivative) function, or simply put a graph which increases in value and then decreases in value periodically. Something like a wriglly snake.

Explanation:

graph{sin(x) [-10, 10, -5, 5]}
This graph for Sin(x)

graph{sin(x) + sin(2x) [-10, 10, -5, 5]}

This is graph for Sin(x) + Sin(2x)

graph{sin(x) +5 [-20, 20, -10, 10]}

This is graph for Sin(x) +5
