Question

Use a calculator to find the approximate value of sin-1( 0.655).

Answer 1

Radian = 0.7142

Degree = 40.92°

Explanation:

Given:
`\sin^(-1)(0.655)`

Let,
`y=\sin^(-1)(0.655)`

It is inverse trigonometry function. We have to use calculator to find angle of trigonometry.

The value of y in two form radian or degree

Using calculator to find the value of y

In radian,

`y=0.7142`

In degree,

`y=40.92^\circ`

Hence, The value of
`\sin^(-1)(0.655)` in radian 0.7142 and in degree 40.92°

Answer 2

arcsin(0.655) ≈ 40.9196° ≈ 0.714183 radians
