how do I get from sin(α) to α?

Example:

sin(α) = -0.6049270855483636374

α = ?

Thanks in advance!

Use the ARCSIN function....also known/labelled as asin sometimes and sometimes as sine inverse (sin^-1)

On the web2.0 calc hit the 2nd button and sin becomes asin.....

Thanks for the quick response!

I tried the asin function on the web2.0calc, but I didn't got what I wanted.

I typed:

sin(46) and got 0.901788347649

but when I tried to reverse it back to 46 I got this:

asin(0.901788347649) equals 1.123889803847.

Am I doing it right?

On the web2.0 calculator hit the 2nd button then the 'sin' button changes to 'asin' hit that button...

then enter ' -0.6049270855483636374' and hit ' = '

NOTE : In lower left corner whether you want degrees or Radians !

The problem was indeed with the calculator setted on Rad instead of Deg...

Thank you very much for your help!
