 Theta is the time offset or phase portion of equation 1. The phase angle defines the offset in time and vice versa. Equation 2 shows the relationship. We happened to choose a particularly common offset of 90°. The phase offset between a sine and cosine wave is 90°. The offset angle is almost always not 90. As a matter of fact is often a function of frequency. Theta is the time offset or phase portion of equation 1. The phase angle defines the offset in time and vice versa.
