How to Use This Calculator

1. Enter the function you want to calculate the integral or derivative of.
2. Enter the variable of integration or differentiation.
3. Enter the interval (a, b) for integration.
4. Click ‘Calculate’.

Formula & Methodology

The integral of a function f(x) with respect to x from a to b is given by the definite integral ∫ from a to b f(x) dx. The derivative of f(x) with respect to x is given by df/dx or f'(x).

Real-World Examples

Example 1: Velocity and Acceleration

If the position of an object is given by s(t) = 3t^2 – 4t + 5, find its velocity and acceleration at t = 2.

Velocity: s'(t) = 6t – 4. At t = 2, v = 6(2) – 4 = 8 m/s.

Acceleration: s”(t) = 6. At t = 2, a = 6 m/s^2.

Example 2: Area Under a Curve

Find the area under the curve y = x^2 from x = 0 to x = 3.

Area = ∫ from 0 to 3 x^2 dx = (1/3)x^3 | from 0 to 3 = 9 – 0 = 9 square units.

Expert Tips

• Always check your answers with a known integral or derivative if possible.
• For complex functions, break them down into simpler parts and calculate each part separately.
• Use the calculator to verify your answers, but also practice calculations by hand for a better understanding.

Interactive FAQ

What is the difference between definite and indefinite integrals?

Definite integrals have a specific interval (a, b), while indefinite integrals do not. Definite integrals yield a numerical value, while indefinite integrals yield a function.

How do I find the antiderivative of a function?

An antiderivative of a function f(x) is a function F(x) such that F'(x) = f(x). You can find the antiderivative of many common functions using integration rules and formulas.
