Find Amplitude, Period, and Phase Shift f(x)=2sin(3x)
Problem
Solution
Identify the standard form of the trigonometric function, which is
ƒ(x)=A*sin(B*(x−C))+D Determine the amplitude by taking the absolute value of the coefficient
A
Calculate the period using the formula
P=(2*π)/B whereB=3
Find the phase shift by identifying the horizontal displacement
C Since there is no value subtracted fromx inside the sine function,C=0
