Q:
# What is the amplitude and period of f(t)= -cos 3t?

Accepted Solution

A:

Answer:option camplitude 1 ; period 2π/3Step-by-step explanation:Given in the question a function,f(t)=-cos3tStandard form of cosine function isf(t)=acos(bt)Amplitude is given by = |a|Period of function is given by = 2π/bSo the amplitude is |-1| = 1 the period is 2π/3 = 2π/3
