General math functions

abs(CArg) Absolute
exp(CArg) Exponential function
ln(CArg) Natural logarithm
log(CArg) Logarithm to base 10
sqr(CArg) Square
sqrt(CArg) Square root
fac(Arg) Faculty
sgn(Arg) Sign
odd(Arg) -1 for even argument, 1 for odd argument
int(Arg) Integer part of argument
s(CArg1,CArg2) Computes the integral of function CArg2 with CArg1 als start value, e. g.: s(0,2*x) will compute x^2
d(CArg) Computes the derivation of function CArg, e. g.: d(x^2) computes 2*x
max(CArg1,CArg2) Determines the larger value out of CArg1 and CArg2
min(CArg1,CArg2) Determines the smaller value out of CArg1 and CArg2
avg(CArg1,CArg2) Computes the average of function CArg2 with CArg1 asa start value (normally 0), z. B.: avg(abs(sin(x))) averages to 2/pi

Arg : Argument, can be a number, a label or a function.

For labels see [Arg] on the operator page.

CArg : for those arguments complex numbers are supported.
