Entering a Function
The input of functions is similar to most computer algebra systems (such as Maple or Mathematica). It should be noted that our parser accepts expressions without an explicit multiplication sign, i.e. 3sin(x)cos(x) is a correct input.
Supported operators
+ addition | != not equal | > greater than |
- subtraction | == equal to | < less than |
* multiplication | >= greater than or equal to | ^ exponentiation |
/ division | <= less than or equal to | - minus (sign) |
! factoral |
Supported functions
with a single argument
exp exponential function | asin arcsine | round rounding |
log natural logarithm (base e) | acos arccos | floor floor function |
sin sine | atan arctan | ceil ceiling function |
cos cosine | sqrt square root | factorial factorial |
tan tangent | abs absolute value | sign sign |
with two arguments
max maximum min minimum atan2 phase
Information on the parser
The parser used by the applets is based on a parser written by Darius Bacon. We complemented the parser with a number of features (e.g. multiplication without an explicit multiplication sign).
