Find Amplitude, Period, and Phase Shift f(t)=1/2*sec(t+2)-pi
Problem
Solution
Identify the standard form of the secant function, which is
ƒ(t)=a*sec(b*(t−h))+k Determine the amplitude. For the secant function, there is no amplitude in the traditional sense because the function is unbounded; however, the vertical stretch factor is
|a|=|1/2|=1/2 Calculate the period using the formula
P=(2*π)/|b| Sinceb=1 the period isP=(2*π)/1=2*π Find the phase shift by solving the argument of the function for
t Settingt+2=0 givest=−2 This indicates a shift of2 units to the left.
