Types of Integrals You Can Solve
A good calculadora de integrales can solve different kinds of integrals:
Indefinite Integrals
These are integrals that don’t have upper and lower limits. When you solve them, you get a function plus a constant (C). For example, the indefinite integral of x² is x³/3 + C.
An indefinite integral looks like this: ∫f(x)dx
Definite Integrals
These integrals have upper and lower limits. When you solve them, you get a specific number. For example, the definite integral of x² from 0 to 1 is 1/3.
A definite integral looks like this: ∫ᵃᵇf(x)dx
Multiple Integrals
Some calculadoras de integrales can also solve double integrals or triple integrals, which are used in more advanced math and physics.
How to Use a Calculadora De Integrales
Using an integral calculator is pretty easy, even if you’re new to calculus. Here’s how to do it:
- Open the calculadora de integrales website or app
- Choose the type of integral you want to solve (definite or indefinite)
- Type in your function using the right symbols (like x² for x squared)
- If you’re solving a definite integral, enter the upper and lower limits
- Click the “Calculate” or “Solve” button
- Look at your answer and the steps the calculator used
Most calculadoras are designed to be user-friendly, with clear buttons and helpful guides.
Common Functions You Can Integrate
A good calculadora de integrales can handle many different types of functions:
- Polynomial functions like x³ + 2x² – 5x + 3
- Trigonometric functions like sin(x) or cos(x)
- Exponential functions like eˣ or 2ˣ
- Logarithmic functions like ln(x) or log₁₀(x)
- Rational functions like 1/(x² + 1)
- Square root functions like √x or √(x² + 1)
You can even combine these functions to make more complex ones, and a good calculator will still be able to solve them.

Integral Calculus Basics for Beginners
If you’re just starting to learn about integrals, here are some basic ideas that will help you understand what a calculadora de integrales is doing:
What Is an Integral?
An integral is a way to find the area under a curve or the total of a changing quantity. It’s the opposite of a derivative, which measures how something changes.
The Fundamental Theorem of Calculus
This important theorem connects derivatives and integrals. It says that if you take the integral of a function’s derivative, you get back to the original function (plus a constant).
Integration Rules
Several rules help with finding integrals:
- The power rule: ∫xⁿdx = xⁿ⁺¹/(n+1) + C (if n ≠ -1)
- The constant rule: ∫a·f(x)dx = a·∫f(x)dx
- The sum rule: ∫[f(x) + g(x)]dx = ∫f(x)dx + ∫g(x)dx
A calculadora de integrales uses these rules and more to solve problems.
