For absolute value, you can use |x| instead of abs(x).
Factorial can be entered using !, e.g. 5! which is 5(4)(3)(2)(1).
The exponential function
e^(x)
can also be entered exp(x).The sign function can also be entered as sgn(). It returns 1, if the input is positive, 0 if the input is 0, and -1, if the input is negative.
For Spanish speakers, sin(x) can also be entered sen(x). Similarly, arcsin(x) = arcsen(x) and sinh(x) = senh(x).
