“`

The constant C is called the “constant of integration” and it can be any real number. The antiderivative of a function is only unique up to a constant of integration.

Here are some additional tips for finding antiderivatives on the TI-84:

  • You can use the “u-substitution” method to find the antiderivative of a function. To do this, first replace the variable x with a new variable u. Then, use the chain rule to find the derivative of the new function. Finally, integrate the new function to find the antiderivative of the original function.
  • You can also use the “partial fraction decomposition” method to find the antiderivative of a function. To do this, first decompose the function into a sum of partial fractions. Then, integrate each partial fraction individually to find the antiderivative of the original function.
  • You can find a more comprehensive list of antiderivatives in a table of integrals.

The TI-84 is a powerful calculator that can be used to perform a variety of mathematical operations, including finding indefinite integrals. By following the steps in this guide, you can learn how to enter an indefinite integral on the TI-84 and find the antiderivative of a function.

4. Press the “ENTER” button.

The TI-84 will then display the indefinite integral of f(x) = x^2, which is x^3/3 + C.

How to Check Your Work

Once you have found the indefinite integral of a function on the TI-84, you can check your work by differentiating the integral. If the derivative of the integral is equal to the original function, then you have found the correct answer.

To differentiate the integral on the TI-84, follow these steps:

1. Press the “2nd” button and select “CALC.”
2. Select “Dif.”
3. Enter the integral you want to differentiate.
4. Press the “ENTER” button.

The TI-84 will then display the derivative of the integral.

Here is an example of how to check your work for the indefinite integral of f(x) = x^2.

1. Press the “2nd” button and select “CALC.”
2. Select “Dif.”
3. Enter “x^3/3 + C”.
4. Press the “ENTER” button.

The TI-84 will then display the derivative of the integral, which is 2x.

Since the derivative of the integral is equal to the original function, we know that we have found the correct answer.

A definite integral is the area under a curve between two specified points. An indefinite integral is the general antiderivative of a function. In other words, it is the function whose derivative is the given function.

How do I find the indefinite integral of a function?

To find the indefinite integral of a function, you can use the following steps:

1. Integrate the function using the power rule.
2. Add a constant of integration.

For example, to find the indefinite integral of the function `f(x) = x^2`, you would use the following steps:

1. Integrate the function using the power rule:

“`
x^2 dx = x^3/3 + C

“`
x^2 dx = x^3/3 + C
“`

What are some common indefinite integrals?

Some common indefinite integrals include:

  • `x dx = x^2/2 + C`
