How to fill out graphing sine and cosine

How to fill out graphing sine and cosine:

First, start by understanding the basic concepts and properties of sine and cosine functions. These functions represent the relationship between angle measures and the corresponding values on the unit circle. Familiarize yourself with the periodic nature of these functions, their amplitude, period, phase shift, and vertical shift.

Next, determine the range of values for the x-axis that you want to represent on the graph. Identify the maximum and minimum values, and calculate the interval between each x-value. This will help you plot a sufficient number of points to accurately depict the sine and cosine waves.

Using the calculated intervals, determine the corresponding y-values for each x-value on the graph. This can be done either manually by computing the sine and cosine values using trigonometric ratios, or by utilizing a graphing calculator or software that can plot these functions automatically.

Once you have a set of x and y coordinate pairs, plot them on the graph paper or using the graphing tool. Start with the initial point (0, 0) on the unit circle and connect the points sequentially to form the sine and cosine waves.

Label the axes with the appropriate units, such as degrees or radians, and include any necessary labels, such as amplitude, period, and phase shift. Consider adding additional details, such as axis labels and a title, to enhance the clarity and understanding of the graph.
