Integral (sin X)/ln X from 0 to 1 in home gives -18.24..., in CAS when I force approx gives [-7.28... -26.80...].

WP 34S iPad app stops at -15.9...

CASIO f'x-CG 10 gives -22.xx... integrated from 1EE-15 to 1-1EE-12

TI NSpire gives infinity (which I suspect may be correct)

What do the amazing mathematicians think on this site?

Prime says "Infinity or undefined limit at bounds ... Returning the last approximations" before returning those values, so they don't mean much.

Wolfram Alpha says "Integral does not converge".

Derive for Windows returns no solution.
