Valid functions and variables
- Variables can be an upper or lower case letter (excluding "e"), and can have subscript using "_", ex.: x_i
- To use unary "-", use "~" or it will show an error message
- You can use the constants e, pi and gr (golden ratio)
- Power was implemented as a^b and square root was implemeted as sqrt(a)
- log and ln were implemented too
- Every trigonometric function were implemented (reciprocals, inverses and hiperbolics too)
- sum(a, b, x_i) = summation of x_i's, with i going from a to b (a and b can be almost anything) (Obs.: don't try to derivate it in x_i!)
- Factorial is not implemented
- You may have to do some algebraic manipulations to simplify the result :)
