The solution of any equations

We solve the equation with unknown x (If it is really problem can be solved)

Step 1. Enter the equation with unknown

Уравнение с неизвестной функциейEquation with unknown  ():
The equality sign in equation
↑ The left side of the equation ↑ The right side of the equation

Examples of solvable equations (simple)

System can not completely solve all equations of the following, but suddenly you're lucky :)

Solution of algebraic (in algebra): square, cubic and other degrees of equations x^4-x=0
Solution of differential equations x'=exp(t)
x''+5*x'+x=0
Decision Trigonometry Equations sin(2*x)=1

Regulation of input equations

In the 'equation' can do the following operations:

Terms of the input functions

In expression f you can do the following operations:
Real numbers
introduce in the form 7.5, not 7,5
2*x
- multiplication
3/x
- division
x^3
- exponentiation
x + 7
- addition
x - 6
- subtraction
Function f may consist of functions (symbols are given in alphabetical order):
absolute(x)
Function - absolute value x (module x or |x|)
