Put your windows calculator to the test.

Open windows calculator, switch to scientific mode.

Enter 0.5 press the "n!" key (factorial key)

Don't cancel that value, now press "X2" key (squared key)

Don't cancel that value now x 4

What do you get?

So that means 0.5! = (sqrt of pi) / 2

Yes, and here are the rest of the particular Gamma function values:

Brilliant isn't it, it's one of my favourite things to show people.

I've some other cool ones, that bring a smile to peoples faces.

I must admit I don't get the deep maths behind it....it's just a fun thing to do with a calculator.
