Question

For the function given, state the starting point for a sample period:

ƒ(t) = −100sin (50t − 20).
plz help

Answer 1

Use the form a sin ( b x − c ) + d to find the amplitude, period, phase shift, and vertical shift.

Amplitude: 100

Period: π / 25

Phase Shift: 2 /5 ( 2 /5 to the right)

Vertical Shift: 0
