Trig Functions

This applet allows you to evaluate trigonometric functions such as sin and cosine and see how their values relate to the unit circle.

Start the Trig. applet by clicking on the above button. Then enter a number in the "Degrees" field, such as 180.

	If you want to evaluate the trig functions at 180 degrees, make sure the "Animation" checkbox on the right is unchecked
	If you want to evaluate the trig functions from 0 to 180 degrees, make sure the "Animation" checkbox on the right is checked

Then click on Add. The trig functions will be evaluated and the number you have entered is added to the "List of angles". You can double-click an existing number in that list to re-evaluate the trig functions at that number (without animation).

You can also choose degrees in radians by picking various multiples of Pi.

Note: The Help button is currently not functioning.
