is cosecant even or odd?

Cosine and secant are even; sine, tangent, cosecant, and cotangent are odd. Even and odd properties can be used to evaluate trigonometric functions.

Cosecant is the reciprocal of sine. Secant is the reciprocal of cosine. Cotangent is the reciprocal of tangent. When solving right triangles the three main identities are traditionally used.

A function f(x) is even if f(−x)=f(x) and function is odd if f(−x)=−x . Hence sin2(x) is an even function.

Answer: The second graph represents an odd function. The graph of an odd function will always be symmetric about the origin.

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.

A: No, the number 300 is not an odd number - it is an even number.

A function f is odd if the graph of f is symmetric with respect to the origin. Algebraically, f is odd if and only if f(-x) = -f(x) for all x in the domain of f. Examples. An interactive LiveMath notebook to visualize symmetry with respect to the origin.

The octet rule is not valid for (d) CO. Explanation: Molecules having an odd number of electrons around them do not follow the octet rule. ... In case of CO, the carbon atom can share at most two electrons from the oxygen atom, therefore a total of 6 valence electrons are present in its outermost shell.

So (it is more-than-odd) and (i.e. 1.4 = 7/5 is still odd), but 1.6 = 8/5 is even.

If two left H-cosets share a common element, then they are equal. Equiv- alently, two left H-cosets that are not equal have no elements in common, i.e., they are disjoint.

A: No, the number 80 is not an odd number - it is an even number.

1. A product of two even functions is even. Therefore, the function x2 cos(2x) is even since both of its factors are even.

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.

No because multiples of odd numbers can be odd or even. When you multiply an odd number by an even number, the answer is always even. For example, 3 x 2 = 6.

2.4 cannot be an even number. Only integers can be odd/even. A fraction cannot be even/odd. It can only be positive/negative.

A number (i.e., integer) expressed in the decimal numeral system is even or odd according to whether its last digit is even or odd. That is, if the last digit is 1, 3, 5, 7, or 9, then it is odd; otherwise it is even. The same idea will work using any even base.

Secant (sec) is the reciprocal of cosine (cos) Cosecant (cosec) is the reciprocal of sin. Cotangent (cot) is the reciprocal of tan.
