http://web2.0calc.com/ I'm using that one

anonymous · Answer

I need to use reverse sine (-1)

anonymous · Answer

Sorry I don't know, try searching it on google.

anonymous · Answer

Anybody?

raden · Answer

you mean to get the value of arc(sin(1)) ?

anonymous · Answer

I've never heard anything about arc. I was told to use reverse sin and that it would be marked as sin -1.

raden · Answer

sin^-1
-1 is the power, right ?

anonymous · Answer

Possibly? I'm going into it blind, I just know its the sine button, but shifted with the -1 bit. It quite possibly is the power.

anonymous · Answer

the way they wrote it, it does look like an exponent

anonymous · Answer

it says to press shift sine to get it

raden · Answer

actually, reverse of sine helps us to find the angle if the value of sine is known

anonymous · Answer

in my instance, I'm using SOH to find an angle that is unknown. The problem turns into sin times the variable equals 3 over five. So that turns into variable =sin^-1 (3/5)

anonymous · Answer

but I need to calculate that exact answer, so how do I do that on a scientific calculator?

raden · Answer

just click 3 : 5, then click 2nd, then click asin, then =

anonymous · Answer

Ok, thank you. It was the pressing 2nd that I didn't know. I wasn't sure which button changed the keys.
