**CURVES AND ANGLE CONVERSION: Sine Curve. **

One cycle of a sine curve is drawn through 360°.

In this example, 0 to 180 degrees are plotted in a positive direction, and 180 to 360 degrees negative. Any instantaneous value of amplitude throughout the cycle can be found by using the trigonometric function Sin.

It will be seen that there is symmetry between the two halves of the sine curve and so 90° and 270° for example, will both have equal, but opposite amplitudes.
