As mentioned above, all the numerical values can be provided as formulas. Formulas can use complex numbers. As mentioned above, all the numerical values can be provided as formulas. Formulas can use complex numbers.
You can use the constants: `pi`, `deg`, `e`, `i`, `inf` (infinity). You can also declare new constants as in `let(tau=2*pi)`. You can use the constants: `pi`, `deg` (pi/180), `e`, `i`, `inf` (infinity). You can also declare new constants as in `let(tau=2*pi)`.
You can use the standard math operators `+`, `-`, `*` (multiplication), `/` (division), `^` (exponentation), and math functions `sin`, `cos`, `tan`, `sinh`, `cosh`, `tanh`, `asin`, `acos`, `atan`, `asinh`, `acosh`, `atanh`, `exp`, `sqrt`, `log` (natural logarithm), `tan`, You can use the standard math operators `+`, `-`, `*` (multiplication), `/` (division), `^` (exponentation), and math functions `sin`, `cos`, `tan`, `sinh`, `cosh`, `tanh`, `asin`, `acos`, `atan`, `asinh`, `acosh`, `atanh`, `exp`, `sqrt`, `log` (natural logarithm), `tan`,
