# Polynomial derivative

This calculator computes a Polynomial derivative.

## How to use this calculator?

Variable Input a single-letter that is the polynomial variable. Examples : polynomial = 4x+1 , then input variable = 'x' polynomial = 9t + 5 , then input variable ='t' Are accepted : The Polynomial variable Polynomial coefficients : must be rational numbers e.g. integer numbers (-4) or fractions (1/4) or decimals (3.6). Operators : + - * / ^ (the last is the power operator so x^2 = x^2) Parentheses : an example of use is (x^2+1)(x-5) Polynomial = x^2-4x+1 (variable = 'x') Polynomial = (x^2-1)(x-5)-3 (variable = 'x') Polynomial = x^3-4/3*x^2+1 (variable = 'x') Polynomial = 0.23*t^2-1/5*t+1/2 (variable = 't')
