Can Anyone solvE or program to differention (mathematics term) problem solved using Any language ?

Question

for e.g-
f(x)=x^3-x^2+x;
(df/dx)=3x^2-2x+1;
differentiation with respect to x. .

Answer 1

d(x^n)/dx = nx^(n-1)
Following this rule if f(x) = x^3 - x^2 + x
we get: d(f(x))/dx = 3x^2 - 2x + 1
Edit: code pending (although its really easy to code)

Answer 2

Math library for js:
(scroll down to examples 5th line has derivative of an expression similar to yours)
