Math Cheatsheet
Constants (Case Sensitive):
- PI: Archimedes' constant (π)
- E: Euler's number (e)
Functions (lowercase, e.g., sin(x)):
- Arithmetic:
+ - * / ^ (power)
- Trigonometric:
sin() cos() tan() asin() acos() atan()
- Logarithmic:
ln() (natural), log() (base 10), exp() (e^x)
- Roots/Power:
sqrt(), pow(base, exp) (also base^exp)
- Misc:
abs() sign() round() floor() ceil()
Parameters:
Lowercase letters a through z (excluding x) can be used as parameters. Their values are set in the "Parameters" section.
Implicit Multiplication:
Multiplication can often be implied (no space needed):
2x → 2*xax → a*x (if 'a' is a parameter)xPI → x*PI(a+b)x → (a+b)*xx(a+b) → x*(a+b)2sin(x) → 2*sin(x)
If separated by spaces, multiplication is also generally implied, e.g., a sin(x) → a*sin(x).
Note: For Constant * Constant or Function * Function, use explicit * (e.g., PI*E, sin(x)*cos(x)).
Typing PISIN will not work as PI*SIN.
Logical Operators:
Can be used in functions for conditional plotting: ? : < > == != && ||
