Is Cos 1 the same as sec?
cos x−1, sometimes interpreted as (cos(x))−1 = 1cos(x) = sec(x) or secant of x, the multiplicative inverse (or reciprocal) of the trigonometric function cosine (see above for ambiguity)
What is the inverse of sin?
Arcsine is the inverse of sine function. It is used to evaluate the angle whose sine value is equal to the ratio of its opposite side and hypotenuse. Therefore, if we know the length of opposite side and hypotenuse, then we can find the measure of angle.
Is sec inverse trig?
For every trigonometry function such as sec, there is an inverse function that works in reverse. These inverse functions have the same name but with 'arc' in front. So the inverse of sec is arcsec etc. When we see "arcsec A", we interpret it as "the angle whose secant is A".
What does sec mean in math?
Secantmore ... In a right angled triangle, the secant of an angle is: The length of the hypotenuse divided by the length of the adjacent side. The abbreviation is sec.
What is sec formula?
Secant is one of the ratios that is derived from the cosine ratio. The secant formula helps in finding out the hypotenuse, the length, and the adjacent side of a right-angled triangle. The formula is sec θ = H/B.

What is Sec Inverse x?
Sec Inverse x is the inverse trigonometric function of the secant function. Mathematically, it is denoted by sec -1 x. It can also be written as arcsec x. In a right-angled triangle, the secant function is given by the ratio of the hypotenuse and the base, that is, sec θ = Hypotenuse/Base = x (say).
Domain and Range of Sec Inverse x
We know that sec inverse x is an inverse function of the secant function. Also, it is necessary for a function to be bijective (one-one and onto) to have an inverse. Hence, to make the secant function bijective, we take the principal value branch as the range of sec inverse x.

The inverse secant function - arcsec
For every trigonometry function such as sec, there is an inverse function that works in reverse. These inverse functions have the same name but with 'arc' in front. So the inverse of sec is arcsec etc. When we see "arcsec A", we interpret it as "the angle whose secant is A".
Large and negative angles
In a right triangle, the two variable angles are always less than 90° (See Interior angles of a triangle ). But we can in fact find the secant of any angle, no matter how large, and also the secant of negative angles. For more on this see Functions of large and negative angles .
Graph of the secant function
Because the secant function is the reciprocal of the cosine function, it goes to infinity whenever the cosine function is zero.
