Question

How to graph trig functions step by step

A) Use linear interpolation.
B) Apply numerical integration.
C) Employ the method of undetermined coefficients.
D) Plot points, identify key features, and use periodicity.

Answer 1

To graph trig functions step by step, start by identifying the key features of the function. Plot points based on these features, and use the periodicity of the function to continue plotting until one full period is completed. Connect the points to create a smooth curve and label important points.

Step-by-step explanation:

How to graph trig functions step by step

1. Identify the key features of the trigonometric function, such as the period, phase shift, and amplitude.
2. Plot points on the graph using the key features. Start with the basic function, such as y = sin(x) or y = cos(x), and then make adjustments based on the given key features.
3. Use the periodicity of the function to continue plotting points until you complete one full period of the function.
4. Connect the plotted points to create a smooth curve on the graph.
5. Label any important points, such as the intercepts, maximum or minimum points, and points of inflection.
