Value of cos inverse 1

Welcome to Omni's cos-1 calculator!

The cos inverse calculator will help you deal with problems that require inverting the cosine function. It can't be any simpler: give us a number between -1 and 1! Why must the number be between -1 and 1? Read on to learn some theory behind the cos inverse, in particular, understand its domain and range or see how to compute the cos inverse of negative values. The cos inverse is the inverse of the cosine function no surprises here. That is, the cos inverse finds the angle that produces a particular cosine value. We denote this function by arccos, and we have the following formula:.

Inverse cosine is an important inverse trigonometric function. Mathematically, it is written as cos -1 x and is the inverse function of the trigonometric function cosine, cos x. An important thing to note is that inverse cosine is not the reciprocal of cos x. There are 6 inverse trigonometric functions as sin -1 x, cos -1 x, tan -1 x, csc -1 x, sec -1 x, cot -1 x. Inverse cosine is used to determine the measure of angle using the value of the trigonometric ratio cos x. In this article, we will understand the formulas of the inverse cosine function, its domain and range, and hence, its graph. We will also determine the derivative and integral of cos inverse x to understand its properties better. Inverse cosine is the inverse function of the cosine function. It is one of the important inverse trigonometric functions. Cos inverse x can also be written as arccos x. Let us consider a few examples to see how the inverse cosine function works.

Wanna learn more about the role of cos-1 in math? We've prepared a brief explanation - scroll down! The inverse of the cosine function is most often denoted by arccos.

Value of cos inverse 1

For any right triangle, given one other angle and the length of one side, we can figure out what the other angles and sides are. But what if we are given only two sides of a right triangle? We need a procedure that leads us from a ratio of sides to an angle.

Compute the cos inverse of the value from Step 1: arccos x. To compute the cos inverse of a negative number -x : Determine the absolute value of your number i. Maths Program. Inverse cosine of x can also be written as cos -1 x or arccos x. It is one of the important inverse trigonometric functions. Satisfied with the results returned by our cos inverse calculator? But please remember what you've learned about the domain of cos inverse! We assume that you have in mind the inverse cosine. As you most certainly remember, the cosine is a periodic function; in particular, it is many-to-one. The inverse sine function, on the other hand, is antisymmetric, i.
