| f'(x) |
The first derivative of f(x) |
| f''(x) |
The second derivative of f(x) |
| integral(integrand, variable,
lower, upper, [resolution]) |
The integral of
integrand with respect to variable from lower to upper - e.g. for ∫01x2dx,
type integral(x^2, x, 0, 1) The resolution is optional input that can be used to increase the accuracy of the integral approximation. |
| t_max |
The maximum value of the
variable or interval t |
| t_min |
The minimum value of the
variable or interval t |
| t_res |
The number of steps of the
variable or interval t |
| scale(t) |
Converts the value of t to a
point in the 0-1 range |
| ipart(x) |
The integer part of x |
| fpart(x) |
The fractional part of x |
| max(a,b,...,h) |
The maximal element of the set |
| min(a,b,....,h) |
The minimal element of the set |
| random |
A random number (Note that this
takes no argument) |
| and, or, <, >, =, true,
false |
Logical operators that return 1
if true, 0 if false |
