Derivative using Wolfram Alpha

**Kataangel** · December 6th 2009, 05:02 PM

Why is Wolfram Alpha calculating this wrong:

$f(u)=(arcsinu)^{-1}$ then what is $f'(\frac{1}{\sqrt2})=$

My calculator says $f'(\frac{1}{\sqrt2})=-2.99547$

Why does Wolfram Alpha say -2.29 instead?

Please explain exactly what you think you mean by $f(u)=(arcsinu)^{-1}$ .

Also please give the exact command string you have given Wolfram Alpha.
