f(x) = { f(x + 1) if x <= 1; x otherwise }, pressing enter before
typing the final "}" will make a new line without submitting.+, -, *, /! Factorial, eg. 5! gives 120% Percent, eg. 5% gives 0.05, 10 + 50% gives
15
% Modulus (remainder), eg. 23 % 3 gives 2You can type special symbols (such as √) by typing the normal function or constant name and pressing tab.
sqrt becomes √deg becomes °pi becomes πsum becomes Σ()integrate becomes ∫()tau becomes τphi becomes ϕfloor becomes ⌊⌋ceil becomes ⌈⌉gamma becomes Γ( becomes ()Variables are defined with the following syntax: name = value
x = 3/4
Functions are defined with the following syntax: name(param1, param2, etc.) = value
f(x) = 2x+3
A(x, y) = (xy)/2
They are used like this: name(arg1, arg2, etc.)
f(3) + 3
A(2, 3)
Derivation can be done like this: name'(arg1)
f'(3) + 3
