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 $ = x^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 $ \frac{2x+3}{3x+9} $ 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+x^2) $ would be sin(2*x+x^2)
