Question
Graph the function. g(x) = 3 cos x
Transcribed Image Text:Graph the function. g(x) = 3 cos x
Expert Solution
Step 1

The graphs of trigonometric functions are very useful in the analysis of waves and simple harmonic motions under engineering mechanics. The graph of sine and cosine functions usually represent the waves in the mechanics. So it becomes important to understand these basic graphs from an engineering perspective.

Step 2

We have to draw the graph of g(x) = 3 cos x

Let's first draw the graph of f(x) = cos x

It can be obtained by creating some data points in a table.
