How do you find the phase shift of the trig function y=4sin (pieX+2) - 5

The phase shift is the value of the angle when the variable

in the angle is zero.

The angle in the sin function in this equation is (pi X + 2).

When the variable 'X' is zero, the angle is 2.

So the phase shift of this sin function is 2 (of whatever

the unit of the angle is ... 2 degrees, 2 radians, etc.)
