[CRASH] Fsolve fails - alexzkter - 06-20-2014 09:25 PM
My physical Prime is failing when inputing this:
![[Image: 15s63o3.png]](http://i57.tinypic.com/15s63o3.png)
I'm getting 2 kind of crashes depending on what my settings on CAS are.
Either this when EXACT, COMPLEX and USE i are unchecked:

...or this when the latter are checked (take a look at the hourglass)
![[Image: 123p9vp.png]](http://i60.tinypic.com/123p9vp.png)
The integers Decimal check box is checked on both cases, and on both calculators.
Someone mind explaining what's wrong?
P.S Solve shows [ ] and Solve app does work and gives proper result.
6030 firmware.

Try fsolve(equation,x,guess) without using brackets []
I get x=168859.63... Which seems to satisfy the equation.
I only use [] with fsolve() for multiple equations. On line help example 1,2 show this.

Unfortunately, I can only debug if the crash happens on the emulator (or in Xcas).

Yes, fsolve(equation,x,0) works, thanks. But so far fsolve[[],[]] sintaxis for a single equation was working for me. Moreover, if it's working on the emulator I don't see why it's not working on the real one, I don't want to have to memorize tons of sintaxys to calculate things... even my Casio FX991ES could solve this equation with its built in solver (after 20 of waiting).
