# How you can use the inverse trig functions on a calculator to find the value ox X for which sin(x)=0.6?

The algotithm is described in explanation

#### Explanation:

The inverse trigonometric function is usually described as "${\sin}^{- 1}$" and usually requires pressing a function key. On PHILIPS calculator it's described as "$2 n d$". So to calculate the angle for which $\sin x = 0.6$ you should:

1) Set the angle unit (radians or degrees) using "$D E G - R A D$" button or simmilar

2) Enter 0.6

3) Press "$2 n d$" to use alternative function.

4) Press "${\sin}^{-} 1$". Usually it's the same button as "sin".

After that you get the angle for which sinus equals to 0.6 in radians or degrees depending on settings in point 1).
