# Calculi

'calculi' is a crate used to algebraically solve equations with unknown variables for a given outcome.

It is also able to solve equations when all unknown variables are given and perform other calculus functions.

# Features

These are the current features of this crate (see Future Features for more info on future features).

- Attempt to algebraically solve equations
- Solve equations with given variables
- Calculate derivatives (and supply them in string/component form)

# Examples

`let` eq1 `=` `calculi``::``Equation``::`new`(``"`x - 2 * a + 4 ^ b`"``)``;`
`assert_eq!``(`eq1`.``solve_for``(``10.``0``,` `vec!``[``(``"`a`"``,` `4.``5``)``,` `(``"`b`"``,` `1.``0``)``]``)``.``1``,` `15.``0``)``;`
`let` eq2 `=` `calculi``::``Equation``::`new`(``"`max(x + 3, root(y, 3), 1) + ln(exp(3))`"``)``;`
`assert_eq!``(`eq2`.``solve_with``(``vec!``[``(``"`x`"``,` `2.``0``)``,` `(``"`y`"``,` `27.``0``)``]``)``.``to_float``(``)``.``unwrap``(``)``,` `8.``0``)``;`
`let` eq3 `=` `calculi``::``Equation``::`new`(``"`x ^ 3`"``)``;`
`assert_eq!``(`eq3`.``derive``(``)``.`text`,` `"`3 * x ^ 2`"``)`

See the documentation for more info on how to use this crate and its functions.

# Future Features

If you want to contribute these are some things you can contribute.

- Calculate primitives (and supply them in string/component form)
- Inverse functions
- Possibly limits (when derivatives and integrals are implemented)
- More calculus...

Fixing possible bugs, shortening code (without making it less efficient) or making it more efficient is of course always welcome.
