Answer:
The curve represented by Green color Dotted Lines in the attached figure represents the Reflection in x-axis of the curve [tex]y = cos x[/tex].
Step-by-step explanation:
As we know, the value of [tex]cosx[/tex] lies between (-1,1) and its graph is a curve. Its value keeps on varying between -1 and 1 only depending on the value of [tex]x[/tex].
The value of [tex]y[/tex] is [tex]\text{0}[/tex] at [tex]x = \frac{\pi}{2}[/tex]. Few values are labeled in the figure attached in the answer. The value [tex]y[/tex] is 1 at [tex]x = 0[/tex].
The curve shown in blue color solid line represents the curve of [tex]y = cos x[/tex].
And the curve shown in the dotted green color in the attached figure represents the reflection in the x-axis.
