Graphs of trig functions
The unit circle definition allows us to define sine and cosine over all real numbers. Doesn't that make you curious what the graphs might look like? Well this tutorial will scratch that itch (and maybe a few others). Have fun.
Determining the amplitude and period of a trig function
Find the amplitude of trigonometric functions.
Find the midline of trigonometric functions.
Find the period of trigonometric functions.
Graphing a sin curve to think about its domain and range.
Basic interpretation of the graph of the cosine function
Thinking about where the graphs of sin and cos intersect.
Understanding how the amplitude and period changes as coefficients change.
Visualizing changes in amplitude and period for a cosine function
Determining a trig function given its graph
