 ## What is an indefinite integral calculator?

An indefinite integral calculator is a tool that can be used to find the antiderivative of a function. The antiderivative of a function is a function whose derivative is the original function. Indefinite integral calculators are useful for a variety of tasks, such as finding the area under a curve or solving differential equations.

## How does an indefinite integral calculator work?

Indefinite integral calculators use a variety of algorithms to find the antiderivative of a function. Some common algorithms include integration by substitution, integration by parts, and integration by partial fractions. The calculator will typically ask you to enter the function you want to integrate and then return the antiderivative of the function.

• Integration by partial fractions: Integration by partial fractions is a technique that can be used to integrate functions that are rational functions.
• Trigonometric substitutions: Trigonometric substitutions are a technique that can be used to integrate functions that contain trigonometric functions.

## When to use an indefinite integral calculator

Indefinite integral calculators can be used for a variety of tasks, such as:

• Finding the antiderivative of a function: Indefinite integral calculators can be used to find the antiderivative of any function, even if the antiderivative cannot be expressed in terms of elementary functions.
• Calculating the area under a curve: Indefinite integral calculators can be used to calculate the area under a curve by finding the antiderivative of the function that represents the curve and then evaluating the antiderivative at the desired endpoints.
• Solving differential equations: Indefinite integral calculators can be used to solve differential equations by finding the antiderivative of both sides of the equation.

## Examples of using an indefinite integral calculator

Here are some examples of how to use an indefinite integral calculator:

• Example 1: Find the antiderivative of `sin(x)`.

To find the antiderivative of `sin(x)`, we can use the following steps:

1. Enter `sin(x)` into the indefinite integral calculator.
2. Click the “Calculate” button.
3. The calculator will return the antiderivative of `sin(x)`, which is `-cos(x) + C`.

Sure. Here is a continuation of the article: Example 2: Calculate the area under the curve `y = x^2` from `x = 0` to `x = 1`.

To calculate the area under the curve `y = x^2` from `x = 0` to `x = 1`, we can use the following steps:

1. Find the antiderivative of `y = x^2`. The antiderivative of `y = x^2` is `x^3/3 + C`.
2. Evaluate the antiderivative at `x = 1` and `x = 0`.
3. Subtract the result of evaluating the antiderivative at `x = 0` from the result of evaluating the antiderivative at `x = 1`.
``````Area = (1^3/3 + C) - (0^3/3 + C)
= 1/3
``````

Example 3: Solve the differential equation `dy/dx = x^2`.

To solve the differential equation `dy/dx = x^2`, we can use the following steps:

1. Integrate both sides of the equation.
``````dy/dx = x^2
∫ dy/dx = ∫ x^2 dx
∫ dy = ∫ x^2 dx
``````
1. Evaluate the integrals.
``````y = x^3/3 + C
``````
1. Solve for `y`.
``````y = x^3/3 + C
``````

## FAQs

### Q.What is the difference between an indefinite integral and a definite integral?

An indefinite integral is an integral that does not have any limits of integration. A definite integral is an integral that has limits of integration. The definite integral of a function is equal to the value of the indefinite integral evaluated at the limits of integration.

### Q.What are the most common mistakes people make when using indefinite integral calculators?

One of the most common mistakes people make when using indefinite integral calculators is entering the function incorrectly. It’s important to make sure you enter the function correctly, as even a small error can lead to an incorrect result.

Another common mistake is forgetting to add the constant of integration. The antiderivative of a function is only determined up to a constant of integration, so it’s important to add the constant of integration to the result.

### Q.What are some good indefinite integral calculators to use?
