Question

Use a calculator to find the values of the inverse trigonometric functions. Round to the nearest degree. sin–1 = __° tan–1(4) =__ ° cos–1(0.1) =__

Answer 1

Well, as you mentioned in the question,

you only need to replace the arguments of those functions in your calculator.

For instance, tan-1(4) = 76 °

and

cos-1(0.1) = 84°

Answer 2

The values of the inverse trigonometric functions:

sin–1 (2/3) = 42°

tan–1(4) = 76°

cos–1(0.1) = 85°

Trigonometry deals with the relationship between the sides and angles of a right-angle triangle. To solve the problem we must know about the concept of trigonometry.

Given: sin–1 (2/3) = °: tan–1(4) = °: cos–1(0.1) = °

How to get the value of the trigonometric function?

sin–1 (2/3) = 41.81° = 42°

tan–1(4) = 75.96° = 76°

cos–1(0.1) = 84.26° = 85°

The value of sin–1 (2/3) = °: tan–1(4) = °: cos–1(0.1) = ° is 42, 76, and 85 degrees respectively.
