Use the unit circle to find the values of the six trigonometric functions for the angle [math]\theta = \frac{7\pi}{4}[/math].
[list=1] [*]Use the unit circle to find the values of [math]\cos \left(\frac{7\pi}{4}\right)[/math] and [math]\sin \left(\frac{7\pi}{4}\right)[/math]. [*]Use the ratio identity [math]\tan \theta = \frac{\sin \theta}{\cos \theta}[/math] to find the value of [math]\tan \left(\frac{7\pi}{4}\right)[/math]. [*]Use the reciprocal identities to find the remaining trigonometric values. [/list] This applet is provided by Walch Education as supplemental material for the [i]UCSS Secondary Math II[/i] program.
