Question

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

Answer 1

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 "`2nd`". So to calculate the angle for which `sinx=0.6` you should:

1) Set the angle unit (radians or degrees) using "`DEG-RAD`" button or simmilar

2) Enter 0.6

3) Press "`2nd`" 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).
