In each one, we are given the value x of the trigonometric function. We are to name the radian angle that has that value. In each case, we must retstrict its range so that the function will be single-valued.The range of y = arctan x...
And in Topic 19 of Trigonometry, we see that the inverse of y = sin x is y = arcsin x.In calculus, the student is expected to know those inverses.One sometimes sees that to "find" the inverse of a function, it is necessary to solve for x and exchange the variables. In fact, ...
To define an inverse trigonometric function, one must insist that for each number in its domain, there corresponds only one number in its range. The domain of the inverse function must be the range of the trigonometric function, and vice versa. The need for such precise definitions of the ...
They aren’t really very useful in trigonometry itself, but are used in integral calculus and some physics or engineering courses. You may wish to skip them, especially on a first reading.After the previous section, you may be wondering about the inside-out versions, taking the arcfunction ...
Use this inverse trigonometry functions tool to find the trigonometric angles in degrees or radians when you know the results of any function.

For every trigonometry function, there is an inverse function that works in reverse. These inverse functions have the same name but with 'arc' in front. (On some calculators the arcsin button may be labelled asin, or sometimes sin-1.) So the inverse of sin is arcsin etc. When we see ...
operation there is an inverse operation that undoes it. Subtraction undoes multiplication and division undoes multiplication. In trigonometry, the arcsin is the inverse of the sin. The inverse of a square root of x isx2Many times calculators have a 2nd key that provides the inverse function. ...
Definition of the arccos function in trigonometry. The inverse of the cosine function. The angle whose cosine is a given number.
What is the cosine of an angle in relation to trigonometry? (a) What does the term inverse trigonometric function mean? (b) How are inverse trigonometric functions used? What is the inverse of sin? When is sin inverse imaginary? What is the cosine of 5pi over 2? What is the cosine of...
