No. The inverse of the secant is called the arc-secant. The relation between the secant and the cosecant is similar to the relation between the sine and the cosine - they are somehow related, but they are not inverse functions.

The secant is the reciprocal of the cosine (sec x = 1 / cos x).

The cosecant is the reciprocal of the sine (cos x = 1 / sin x).

Are secant and cosecant inverse of each other?

No.


What is the inverse sine function?

The inverse sine is the cosecant, otherwise known as "hypotenuse over opposite" or arcsine. The cosecant is often confused as being the inverse of the cosine, which, in reality, is the secant, otherwise known as "hypotenuse over adjacent" or arccosine.


The inverse of the cosine function?

The inverse of the cosine is the secant.


What is reciprocal in trigonometry?

The inverse of sine (sin) is cosecant (csc). The inverse of cosine (cos) is secant (sec). The inverse of tangent (tan) is cotangent (cot).


What is an arccosecant?

An arccosecant is the function which is the compositional inverse of the cosecant function.

Why dont you have buttons for cotangent secant cosecant?

You don't have buttons for cotangent, secant, and cosecant because you don't need them. Just invert. Cotangent is 1 over tangent, secant is 1 over sine, and cosecant is 1 over cosine.

What is an inverse cosine?

The inverse of the cosine is the secant.


What is an secant in math?

Secant is a trignometric function. In a right triangle, the secant of an angle is the hypotenuse over the adjacent side. It is also the inverse of cosine. For example secant(x) = 1/cos(x)


Why is the secant function is an even function and the tangent and cosecant are odd functions?

I find it convenient to express other trigonometric functions in terms of sine and cosine - that tends to simplify things. The secant function is even because it is the reciprocal of the cosine function, which is even. The tangent function is the sine divided by the cosine - an odd function divided by an even function. Therefore it is odd. The cosecant is the reciprocal of an odd function, so it is naturally also an odd function.

If the value of a sine function is 0 then the co-secant function is undefined?

That's right. cosecant(x) = 1 / sine(x), so you would get a division by zero.
