question sinus

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!
