Question

If y = cos x, then what is the maximum value of y?

a) 1
b) -1
c) π
d) 2π

Answer 1

The maximum value of y will be 1 as cos0=1 is maximum value for cos

Option (a)

Hope it may help you...

Answer 2

Answer:

The maximum value of the cosine function is found to be option (a): 1.

Step-by-step explanation:

We know that the cosine function, $cos(x)$ gives us a oscillatory graph revolving back and forth between two values with the minimum value of the function being -1 at $x=-\frac{\pi}{2}$ and the maximum value of the function being 1 at the location, $x=0$.

Thus, the maximum value of y for $y=cos(x)$ is found to be 1.
