Factorize & Expand Functions

Factorize a polynomial

Enter a function (e.g. x^2+2*x+1 ):

Expand a polynomial

Enter a function (e.g. (x+1)*(x+2) ):

Simplify trigonometric expressions

Enter a function (e.g. sin(x)^2+cos(x)^2 ):

Expand trigonometric expressions

Enter a function (e.g. cos(x)*cos(3*y)-sin(x)*sin(3*y) ):

Simplify rational expressions

Enter a function (e.g. (x^2+2*x+1)/(x+1)+1/(4*x+3) ):

Expand rational expressions

Enter a function (e.g. (x^2-1)/(x+2) ):

 

How To Enter Equations.

To successfully use this tool you must follow these rules on how to construct your equations. 
  1. Operators:
    • * - multiplication
    • / - division
    • + - plus
    • - minus
    • ( ) - brackets
    • ^ - power e.g x 2 = 2^2
  2. You must enter all operators.  For example 2x+3 would be 2*x+3, note that you must show the multiplication sign.
  3. If you have a fraction like you must enter both numerator and denominator in brackets, so the above function would become (2*x+3)/(3*x+9)
  4. Built-in functions:
    • sin(x), cos(x), tan(x) - Trigonometric functions.
    • asin(x), acos(x), atan(x) - Inverse Trigonometric functions.
    • sinh(x), cosh(x), tanh(x) - Hyperbolic Trigonometric functions.
    • log(x) - Natural Logarithm.
    • log10(x) - Log base 10
    • exp(x) - exponential, ex
  5. You can put functions within built-in functions for example sin(2x+x2) would be sin(2*x+x^2)
