(tg9ctg9 + 9) * 9 / 9 = 10
Eh, yeah, there really are tons of possibilities.
Ok, let's make 1 to 100 with five 9. (with only + - * /, hence no trigonometry, logarith ...[text shortened]... sions, calculus, combinatorics and other creepy stuff)

anyway...........WOW!
yeah.. didn't read from beginning...
but sqrt x = x^(1/2), it doesn't make a lot of sense to use it too....
I guess 43 is impossible with only those combinations...
43= sqrt(9)*9 + sqrt(9)*9 -9/9 ->another with six "9" .

I think, 66 is a good number to stop the project now.
With the sqrt9-trick for 3, the (sqrt9)!-trick for 6 and
the the (sqrt9)!/sqrt9 for 2 and the ^9 trick
( (9/9)^9=1, (9-9)^9=0)
the rest is just easy going
