The degree measure of an angle is commonly expressed as a ratio. For instance, the arctangent of an angle is approximately 0.753 radians. It is calculated by dividing y-1 by tan(y). The inverse function of tan(y) is a radian to the nearest whole number.

In geometry, angles are measured by their radians, which are units of measurement. One radian is one half-degree, while three-thirds of a degree is equal to three-fourths of a degree. The cotangent of an angle equal to 3.73 is equal to half-a-radian, and the secant equal to one-third of a radian.

## arctangent (3.73) is approximately 1 radian to the nearest whole number

An arctangent is the inverse of a tangent trigonometric function. It’s also called arcus tangens and is sometimes written as tan-1(x). It’s useful in obtaining the angle of a given number from a tangent trigonometric ratio, or the ratio between the two sides of a triangle.

## Co-function of a tangent

The co-function of a tangent angle is a function that combines the cosine and sine functions of the angle. These two functions are equal if the sum of their cotangents is 90 degrees. Thus, the co-function of a tangent angle is the cosine of its complement.

A tangent function has a fixed domain. In other words, it’s undefined at any angle other than 90 degrees. The domain of a tangent function includes all real numbers except cos(th), which is 0 in the tangent domain. The domain is symmetric around the origin, and the tangent is symmetric.

Using a co-function identity calculator will help you find the cosine and cotangent angles of any angle. In this way, you can write any expression relating to these angles as a function of the other angles in the triangle. In the case of tangent angles, it’s also possible to write the cosine of a tangent angle as the cotangent of a tangent angle.

In addition, the cosine and sine functions of a tangent angle can also be computed. The two functions have mutual reflections in the interval (0deg-90deg). These functions only work for angles that are between 0 degrees and 90 degrees.
