By definition, we have to:
 In mathematics, the curve that graphically represents the sine function and also the cosine function is called sinusoid.
 It is a curve that describes a repetitive and smooth oscillation.
 Therefore, the following function is not a sinusoid:
 [tex]y= \sqrt{x} [/tex]
 Answer:
 
y= Sqrtx

The function that is not a sinusoid is the second option:

y = √x

Which function is not a sinusoid?

A sinusoid is a function that is related to the sine function.

Obviously, the first function sin(x) is a sinusoid.

And the third function:

y = cos(x)

If we differentiate, we get:

dy/dx = -sin(x).

Also related to the sine function.

Finally, the second option is a square root, it is not related to trigonometric functions, then the correct option is that one.

The function that is not a sinusoid is:

y = √x
