Question

What is the amplitude of the sinusoids function m(x)= -3.5 cos x

Answer 1

Answer:

The amplitude  of the given sinusoidal function is 3.5

Step-by-step explanation:

The given sinusoidal function is

$m(x)=-3.5\cos x$

This function is of the form:

$m(x)=a\cos bx$

where

a=|-3.5|=3.5 is the amplitude.

Therefore the amplitude of the given sinusoidal function is 3.5
