Question

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

Answer 1

The amplitude of the given sinusoidal function is 3.5

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
