The allowed functions are: ln(x), log(x), sen(x), sin(x), cos(x), tan(x), cot(x), sec(x), csc(x), abs(x), asen(x), asin(x), acos(x), atan(x), acot(x), asec(x), acsc(x), senh(x), sinh(x), cosh(x), tanh(x), sech(x), csch(x), coth(x), asenh(x), acosh(x), atanh(x), asech(x), acsch(x), acoth(x), sqrt(x), round(x). me(x) ->integer maximum, rnd() -> random numbers, sgn(x) -> Sign function, pi -> constant PI, e -> constant e. potency: x^2 rest: x%2
