## Is sin x cos X even function?

Since sin(x)+cos(x)=sin(x)+cos(x) sin ( x ) + cos ( x ) = sin ( x ) + cos ( x ) , the function is even.

## Is the function f/x cos x an odd function?

Explanation: cos(x)=cos(−x) , therefore cosine is an even function.

**Is x sin x even or odd?**

Odd functions have symmetry about the origin. thus xsinx is an even function.

**Is sin2x even or odd?**

sin 2x is an odd function.

### Does sin x sin x?

Because sin(2π-x) lies on the fourth quadrant where sin is negative, so sin(-x) = -sin x whereas cos(2π-x) also lies on the same quadrant but cos is positive in that quadrant which gives cos(-x) = cos x.

### Is x sin x odd or even?

**Is FX sec x odd or even?**

If a function is odd, f(−x)=−f(x) , which means that its graph is symmetric with respect to the origin. In this case, we can see that the graph is symmetric with respect to the y -axis. Thus, f(x)=secx is an even function.

**Why is sin x an odd function?**

A function is called even if its graph is symmetrical about the y_axis, odd if its graph is symmetrical about the origin. If f(−x)≠f(x)orf(−x)≠−f(x) the function is not even or odd. Now the answer you need: the function y=sinx is odd, because sin(−x)=−sinx.

#### Is x 2 odd or even?

For example, f(x) = x2 is even function. If we substitute x with -x in the function and it neither satisfies f(x) = – f(-x) nor f(x) = f(-x), then the function is neither even function nor odd function.

#### Is cos3x even or odd?

Therefore, cos3(−x)=cos(−x)cos(−x)cos(−x)=cosxcosxcosx=cos3x (i.e. cos3x must be even function).

**Is the function f (x) = cos x sin x even or neither?**

Is the function f (x) = cos x sin x even, odd or neither? f (x) = cos(x) ⋅ sin(x) is an odd function. Therefore, f (x) = cos(x) ⋅ sin(x) is an odd function.

**Why is sin(−x = -sinx) an odd function?**

Explanation: By definition, a function f is even if f(−x) = f(x). A function f is odd if f(−x) = −f(x) Since sin(−x) = −sinx, it implies that sinx is an odd function. That is why for example a half range Fourier sine series is said to be odd as well since it is an infinite sum of odd functions.

## Is the cot (-X) function odd or even?

Cotangent function is odd. cot (-x) = – cot x Determine Whether A Trigonometric Function Is Odd, Even, Or Neither Examples with Trigonometric Functions: Even, Odd or Neither Cosine function, Secant function, Sine function, Cosecant function, Tangent function, and Cotangent function

## Which trigonometric function is odd?

Tangent function is odd. tan (-x) = – tan x Cotangent function is odd. cot (-x) = – cot x Determine Whether A Trigonometric Function Is Odd, Even, Or Neither Examples with Trigonometric Functions: Even, Odd or Neither
