Rational Function Calculator – Simplify and Graph Functions Online

This rational function calculator helps you quickly find the simplified form of any ratio of two polynomials.

How to Use the Calculator

Enter the coefficients of your rational function in the format “ax^b+cx^d+…” where a, b, c, d,… are numerical values, in the numerator and denominator fields. For example, use “2x^2+3x+1” format without any spaces. You must also provide the value of x to evaluate the function at that point.

How the Calculator Works

The calculator parses the polynomials for both numerator and denominator, evaluates them using the provided x-value, and then divides the results from the numerator by the denominator to provide the output.

Limitations

This calculator only works with polynomials that have their terms separated by ‘+’ or ‘-‘ and their powers denoted by ‘^’. It does not support any implicit multiplication without an asterisk, nor does it handle any other functions like trigonometric, exponential or logarithmic functions.
