Inverse Trig Functions Worksheets
What are Inverse Trig Functions?
In the world trigonometry, some functions are extensively used for a higher level of problems, i.e., the inverse trigonometric functions. You are aware of the trigonometric functions (sin, cos, and tan), which is used to find the unknown side length of a right triangle. The inverse trigonometric functions sin1, cos1, and tan1 are used to find the unknown measure of the angle of a rightangled triangle when you are of the two side lengths.
In other words, the inverse trigonometric functions sin1, cos1, and tan1 can be denoted as 1/sin, 1/cos, and 1/tan respectively.

Basic Lesson Guides students solving equations that involve an Inverse Trig Functions. Demonstrates answer checking. Find the value of Θ in radians considering the principal inverse function: Θ = arc sin(√3/2). The inverse function arcsin(x)= sin1(x)and arcsin can be read as “the angle whose sine is”. According to the question it means the angle whose sin is √3/2.
