Question

How do you graph two complete cycles of `y=-cos(2t)`?

Answer 1

Set up a table of 'y' and 't' values and calculate the values from `0 to 720` (or `0 to 4pi`) in the expression. Plot the pairs of numbers on a graph paper or use a computer program.

Explanation:

This example produces this curve for ONE cycle:

To make a graph for two cycles, just copy this one on to the end of it. (or generate another set of values)
