Pts calculate the phase angle between two sinusoidal functions

To calculate the phase angle between two sinusoidal functions, we need to compare their arguments (the expressions inside the trigonometric functions). Let's compare the arguments of the given functions:

V1 = 3cos (wt + 40)

40 = -50

This equation is not possible. It implies that there is no phase angle between V1 and V2 since they do not have a common argument. However, we can still determine which sinusoid is leading by comparing the phase shifts.

- There is no phase angle between V1 and V2 since their arguments are not equal.

- V1 (3cos (wt + 40)) is leading V2 (-2sin(wt - 50)) due to its positive phase shift.
