Given:

[tex]f(x)=\frac{1}{2}cos(x)[/tex]

Required:

We need to find the amplitude of the equation.

Explanation:

The given equation is of rhe form

[tex]f(x)=Acos(Bx)+D[/tex]

Where A =1/2, B=1, and D=0.

We know that A is the amplitude.

[tex]Amplitude\text{ =}\frac{1}{2}[/tex]

Final answer:

[tex]Amplitude\text{ =}\frac{1}{2}[/tex]
