This lesson discusses radian measure and how it relates to measuring angles in degrees, leading to converting between the measurement systems. There are also a few examples involving measuring angles in radians.

This tutorial shows how to graph the sine and cosine functions in degrees. Common characteristics, such as max and min points, amplitude and period are also discussed for the two sinusoidal functions.

This lesson shows how to graph the reciprocal trigonometric functions (y = cscx, y = secx and y = cotx) using the y = sinx, y = cosx and y = tanx functions.

This lesson shows examples of graphing transformed y = sinx and y = cosx graphs (including changes in period, amplitude, and both vertical & horizontal translations). There is also an example of how to graph y = tanx using the y = sinx and y = cosx functions.

This tutorial shows how to graph y = a sin [k(x - d)] + c and y = a cos [k(x - d)] + c plus an example involving an application of trigonometric functions.

This lesson demonstrates how to use transformations to sketch the graphs of sinusoidal functions.

This tutorial shows how to use sinusoidal functions to model real world phenomena.
