Evaluating Inverse Trigonometric Functions Basic Introduction Using a calculator to evaluate inverse trigonometric functions. to evaluate inverse trigonometric functions that do not involve the special angles discussed previously, we will need to use a calculator or other type of technology. most scientific calculators and calculator emulating applications have specific keys or buttons for the inverse. This trigonometry video tutorial provides a basic introduction on evaluating inverse trigonometric functions. it has plenty of examples such as inverse sin.
Evaluating Inverse Trigonometric Functions Youtube One of the more common notations for inverse trig functions can be very confusing. first, regardless of how you are used to dealing with exponentiation we tend to denote an inverse trig function with an “exponent” of “ 1”. in other words, the inverse cosine is denoted as cos−1(x) cos − 1 (x). it is important here to note that in. Inverse functions allow us to find an angle when given two sides of a right triangle. in function composition, if the inside function is an inverse trigonometric function, then the result of the composition is an exact expression; for example, \sin ( {\cos}^ {−1} (x))=\sqrt {1−x^2}. Lesson 3: inverse trigonometric functions. intro to arcsine. evaluate inverse trig functions. restricting domains of functions to make them invertible. The inverse sine function. the function f(x) = sin − 1x is defined as follows: sin − 1x = θ ifandonlyif sinθ = x and − π 2 ≤ θ ≤ π 2. in other words, sin − 1x is the angle in radians, between − π 2 and π 2, whose sine is x. there are many angles with a given sine value x, but only one of these angles can be sin − 1x.

The inverse sine function. the function f(x) = sin − 1x is defined as follows: sin − 1x = θ ifandonlyif sinθ = x and − π 2 ≤ θ ≤ π 2. in other words, sin − 1x is the angle in radians, between − π 2 and π 2, whose sine is x. there are many angles with a given sine value x, but only one of these angles can be sin − 1x. To evaluate inverse trigonometric functions that do not involve the special angles discussed previously, we will need to use a calculator or other type of technology. most scientific calculators and calculator emulating applications have specific keys or buttons for the inverse sine, cosine, and tangent functions. To find the domain and range of inverse trigonometric functions, switch the domain and range of the original functions. each graph of the inverse trigonometric function is a reflection of the graph of the original function about the line y=x y = x. figure 4. the sine function and inverse sine (or arcsine) function.
