are trig functions even or odd?

The majority of functions are neither odd nor even, however, sine and tangent are odd functions and cosine is an even function.

Sin (x) is an odd function because sin(-x) = -sin(x). It's graph is symmetric to the origin. Cos (x) on the other hand is an even function cos (-x) = cos (x), and its graph is symmetric to the y-axis.

The only function that is both odd and even is f (x) = 0. If a function is odd, the absolute value of that function is even.

2sinx is twice the trigonometric function sinx whereas 2x in sin2x represents angle. Sin(x) is a function. Twice that function is 2sin(x).

A function f is even if the graph of f is symmetric with respect to the y-axis. Algebraically, f is even if and only if f(-x) = f(x) for all x in the domain of f. A function f is odd if the graph of f is symmetric with respect to the origin.

f(x) = |x| It makes a right angle at (0,0) It is an even function. Its Domain is the Real Numbers: Its Range is the Non-Negative Real Numbers: [0, +∞)

It is indeed true that "whenever both x and −x are in the domain of the square root function the function values agree" because (as you know quite well) only x=0 satisfies that hypothesis. So according to the strict reading of the definition, the square root function is even.

we know if tan(A) = x, then tan(-A) = -x. i.e if A = arctan(x), -A = arctan(-x), or arctan(x) + arctan(-x) = 0, therefore arctan(x) is odd.

The inverse of tangent is denoted as Arctangent or on a calculator it will appear as atan or tan-1. Note: this does NOT mean tangent raised to the negative one power. ... Sine, cosine, secant, tangent, cosecant and cotangent are all functions however, the inverses are only a function when given a restricted domain.

A function is even if f(−x)=f(x) f ( - x ) = f ( x ) . Check if f(−x)=f(x) f ( - x ) = f ( x ) . Since 1x2=1x2 1 x 2 = 1 x 2 , the function is even.

Even functions are symmetrical about the y-axis. Odd functions have symmetry about the origin. thus xsinx is an even function. This is graph of xsinx.

Domain: So the domain of f(x) := tanx is all real numbers except x = π 2 + kπ, k an integer. All of the trig functions are periodic and thus are not one-to-one.

symmetry: since tan(-x) = - tan(x) then tan (x) is an odd function and its graph is symmetric with respect the origin. intervals of increase/decrease: over one period and from -pi/2 to pi/2, tan (x) is increasing.

A function with a graph that is symmetric about the origin is called an odd function. Note: A function can be neither even nor odd if it does not exhibit either symmetry. For example, f(x)=2x f ( x ) = 2 x is neither even nor odd.

1 Answer. As #cos (-x)=cos x, f(-x)=f(x). So, f(x) is an even function.

This is a bit surprising given our initial definitions. and the hyperbolic sine is the function sinhx=ex−e−x2. Notice that cosh is even (that is, cosh(−x)=cosh(x)) while sinh is odd (sinh(−x)=−sinh(x)), and coshx+sinhx=ex.

Trigonometric functions describe the relation between the sides and angles of a right triangle. ... These functions often appear in the solution of differential equations and functional equations. The trigonometric functions include the following 6 functions: sine, cosine, tangent, cotangent, secant, and cosecant.
