Find Amplitude, Period, and Phase Shift y=-5sin(1/2x)
Problem
Solution
Identify the standard form of the trigonometric function, which is
y=A*sin(B*(x−C))+D Determine the amplitude by taking the absolute value of the coefficient
A
Determine the period using the formula
P=(2*π)/|B| whereB=1/2
Determine the phase shift by identifying the horizontal displacement
C Since there is no value subtracted fromx inside the sine function,C=0
