Inverse trigonometric functions are known as the inverse functions of basic trigonometric functions that are sine, cosine, tangent, cotangent, cosecant, and secant functions. These functions are majorly used in the field of engineering, physics, geometry and navigation.

In most of the entrance examinations after 12t standard, the Inverse Trigonometric functions topic is included in the Mathematics section.

The inverse trigonometric functions perform the opposite function of trigonometric functions that are sine, cosine, tangent, cotangent, cosecant, and secant. They are also known as "Arc Functions" as for a given value of trigonometric functions they provide the length of the arc needed to obtain that particular value.

Inverse Trigonometric Function Questions and Answers for DU JAT

Here is the list of sample Inverse Trigonometric Function questions curated from previous year DU JAT Question Papers. Our expert from Supergrads has solved the questions. Go through the questions along with detailed solutions and enhance your preparation for the upcoming DU JAT exam.

1. Find the value of cos^{-1}(1/2) + 2 sin^{-1}(1/2)

π/3 + π/6 = 2π/3

2. Find the value of tan^{-1}(2 cos (2 sin^{-1}(-1/2)))

3. Find the value of tan^{-1}(√3) + sec^{-1}(-2)

4. Find the value of Sin [π/3 - sin^{-1}(-1/2)]

Sin [π/3+π/6] = Sin (π/2) = 1

5. Find the value of Sin (1/2 cos^{-1} 4/5)

Let us consider: Sin (1/2 cos^{-1} 4/5) = SinΘ/2 ; cos^{-1} 4/5 = cosΘ = 4/5

6. Evaluate Sin(2 cos^{-1} (-3/5) )
