Final answer:
The subject of this question is Trigonometric equations and how they relate to sinusoidal functions. A graphing calculator can be used to plot the graph of a sinusoidal function based on its equation.
Step-by-step explanation:
The subject of this question is Trigonometric equations. Sinusoidal functions are periodic functions that can be represented by trigonometric equations, specifically sine and cosine functions. These functions graph as periodic waves and can be used to model various phenomena, such as the motion of a pendulum or the behavior of waves.
To graph a sinusoidal function, you can use a graphing calculator that allows you to input the equation and plot the corresponding points. This will give you the graph of the function, which shows how the function varies over its period.
For example, if you have the equation y = 3sin(2x) + 2, you can input this into a graphing calculator to see the graph of the function. It will show the periodic oscillation with an amplitude of 3 and a period of π/2, as well as a vertical shift of 2 units.
