1.
A
normal sine wave can be represented as,
2.
If the waveform is shifted to the
right or left of 0°, the expression becomes
where theta is
the angle in degrees or radians that the waveform has been shifted.
3.
If the waveform passes through the
horizontal axis with a positive going (increasing with time)
slope before 0°, as shown in Figure 2, the expression is:
