The Integral Formula

The fundamental theorem of calculus connects differentiation and integration. For a function f(x), the definite integral from a to b is given by:

Definite Integral Formula

∫_a^b f(x) dx = F(b) - F(a)

where F(x) is the antiderivative of f(x).

For indefinite integrals, the result is the antiderivative plus a constant of integration:

Indefinite Integral Formula

∫ f(x) dx = F(x) + C

where C is the constant of integration.

The calculator uses these fundamental principles to compute integrals accurately.

Worked Examples

Let's look at some examples to see how Integral Calculator Desmos works in practice.

Example 1: Definite Integral

Calculate the definite integral of x² from 0 to 1.

Enter the function: x²
Enter lower limit: 0
Enter upper limit: 1
Click "Calculate"

The result should be 0.333..., which is 1/3.

Example 2: Indefinite Integral

Find the antiderivative of sin(x).

Enter the function: sin(x)
Leave limits blank for indefinite integral
Click "Calculate"

The result should be -cos(x) + C, where C is the constant of integration.

Note

For more complex functions, the calculator may provide step-by-step solutions or additional details about the integration process.
