Simple solution of complicated math problems!
This website can solve any equation with one variable. If you're having problem solving some equations, just type them below, and the solutions will appear at a glance! The program can solve linear equation, quadratic equation, polynomial equation, homological equation, equation with absolute value, and even trigonometric equation! The Program can find even 10 solutions, so it has greater capabilities than most calculators ;-)
x - Variable in equation
+ - * / - Basic arithmetic operations
x^y - Raises x to power y
sqrt(x) - Calculates square root of the expression in brackets
abs(x) - Calculates the absolute value from expression in brackets
sin(x) - Calculates sinus of the expression in brackets
cos(x) - Calculates cosinus of the expression in brackets
tan(x),tg(x) - Calculates tangent of the expression in brackets
exp(x) - Calculates 
ln(x) - Calculates natural logarithm of the expression in brackets
Constants
pi - 3,14159265...
e - 2,71828183...
Example
(x-1)*(x+8)=0
sin( 2x )+cos( x + pi/2 )=sqrt(3)/2
2x^3 - 3x^2 + x - 1 = 0
ln(x)=e
