Polynomial calculus

Evaluate the derivative and definite integral of ax² + bx + c.

How this works

For f(x)=ax²+bx+c, f′(x)=2ax+b and F(x)=ax³/3+bx²/2+cx. Integral = F(upper)−F(lower).

Example

Using the example inputs, derivative at x is 4.

a coefficient
1
b coefficient
0
c coefficient
0
Derivative at x
2
Integral lower bound
0
Integral upper bound
3
Derivative at x

The integral is signed area; reversing bounds changes its sign.

Scope and assumptions

Polynomials through degree 2 only. No general integrals, limits, or symbolic expression input.
