Find Amplitude, Period, and Phase Shift y=-3sin(-6x+pi/2)
Problem
Solution
Identify the standard form of the trigonometric function, which is
y=A*sin(B*(x−h))+k ory=A*sin(B*x−C)+k In this equation,A=−3 B=−6 andC=−π/2 Calculate the amplitude by taking the absolute value of the coefficient
A
Calculate the period using the formula
P=(2*π)/|B|
Calculate the phase shift by setting the argument of the sine function to zero and solving for
x or using the formulaC/B from the formB*x−C
