This is driving me mad...
Can anyone tell me how to do the following equation on a calculator?
1 / [1 + e-(1*0.5+1*0.4-1*0.8)]
Cheers,
TK
Oh, I see
e has a value approaching 2.7. Actually it's e^(...).
It's the exponential function : Exponential function - Wikipedia, the free encyclopedia
So if you want to enter the function in your calculator, it should be :
1/(1+e^(-(1*0.5+1*0.4-1*0.8)))
Thanks.
I know the result should be 0.5250 according to the textbook I am using. But doing the above in my calculator returns 0.5 for some reason.
Another similar example that is given is:
1/(1+e^(-(1*0.9+1*1.0+1*0.1)))
This should return 0.8808 but also returns 0.5 on my calculator.
If it helps the calculator is a Sharp EL-530L.
