The inverse of the cosine function is arcosine. The domain is −1 ≤ x ≤ 1 since the range of the cosine function is from -1 to 1. The range is from 0 to pi radians or 0 to 180 degrees.

Is the inverse function of secant is the cosecant function?

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).

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.

Concepts of inverse trignometric?

I think you mean the concept of inverse trig functions.Let's just look at one, the inverse cosine function.cos-1 (x) also called arccos(x) is the inverse of cos(x).cos-1 (x) x=cos (theta)So to evaluate an inverse trig function we are ask what angle, theta, did we plug into the trig function (regular, not inverse function) to get x.So here is one more example.tan-1 (x) means x=cos (theta)
