## What is an Indefinite Integral?

Indefinite integral is a basic process of integration in calculus in which the **indefinite integral** represents a family of functions F(x) whose derivative gives back the original function f(x), up to a constant C.

$$ \int f(x)\; dx \;=\; F(x) + C $$

Where F(x) is an antiderivative of integral function f(x), and C is the integration constant. The above rule shows that F(x) is a set of functions that are separated by a constant in a definite integral.

## How to Calculate Indefinite Integrals?

Indefinite integral calculator with steps helps to calculates the antiderivative of a function f(x) because it uses the **direct rule** of integration during the calculation.

Unlike definite integral where you apply the limit values after integration, you just integrate the given function only. Here are the step-by-step procedures on how to compute indefinite integrals:

**Step 1: **Determine the indefinite integral function f(x) that you want to integrate.

**Step 2:** Apply the integration rules that give an appropriate solution for the given function f(x). These common rules include:

**Power Rule:**

When you have a function in **exponential power** you can apply the power rule where 1 is added to the exponential power and the new value is divided by that number.

$$ \int x^n\; dx \;=\; x^n + \frac{1}{n + 1}\; for\; n ≠ −1 $$

**Constant Multiple Rule:**

When the given function is multiple of a constant then you can integrate the given function f(x) only, keeping the constant outside the integral.

$$ \int a . f(x)\; dx \;=\; a . \int f(x)\; dx $$

**Sum/Difference Rule:**

For the **sum and difference** of two functions f(x) and g(x) rules, separate both the functions and then integrate them with respect to the variable of integration.

$$ \int (f(x) \pm g(x)) dx \;=\; \int f(x)\; dx \pm \int g(x)\; dx $$

**Exponential and Logarithmic Rules:**

For the exponential function, integration is the same original function as shown in the below rule. For logarithmic function, indefinite integration is the derivative of the given function.

$$ \int e^x\; dx \;=\; e^x + C,\; \; \; \int \frac{1}{x} dx \;=\; ln |x| + C $$

**Trigonometric Rules:**

For finding the trigonometric functions, the indefinite integral calculator uses integral rules. Nevertheless, the inverse trigonometric rules are also present in the rules of integration.

$$ \int sin(x)\; dx \;=\; - cos(x) + C $$

$$ \int cos(x)\; dx \;=\; sin(x) + C $$

$$ \int tan(x)\; dx \;=\; sec^2(x) + C $$

**Step 3:** After applying the appropriate rule,solve the integral F(x): ∫f(x)dx = F(x) + C, where F(x) is the antiderivative of f(x), and C is the constant of integration.

**Step 4: **For more complex integrals, some other methods can also be used that are the U substitution or integration by parts method, and the trigonometric substitution method to integrate the given indefinite integral function.

## Solved Example of Indefinite Integral:

Let's see an **example** of indefinite integral with solution function which will help us to understand the working process of indefinite integrals calculator.

### Example: Evaluate the indefinite integral

$$ \int (5x^3 - 7x^2 + 3x + 4) dx $$

**Solution:**

Separate the integral for each value,

$$ \int (5x^3 - 7x^2 + 3x + 4) dx \;=\; \int 5x^3 dx - \int 7x^2 dx + \int 3x\; dx + \int 4\; dx $$

Separate the constant by using constant multiple rule,

$$ \int 5x^3 dx - \int 7x^2 dx + \int 3x\; dx + \int 4dx \;=\; 5 \int x^3 dx - 7 \int x^2 dx + 3 \int x\; dx + 4 \int 1\; dx $$

Apply the direct rule for integration on the given indefinite integral function and then simplify it to get solution.

$$ \int (5x^3 - 7x^2 + 3x + 4) dx \;=\; \frac{5}{4}x^4 - \frac{7}{3}x^3 + \frac{3}{2}x^2 + 4x + C $$
