Introduction

In this article, we will explore the use of the table of integrals to evaluate a given integral. The table of integrals is a collection of known integrals that can be used to solve a wide range of problems. In this case, we will use the table of integrals to evaluate the integral $\int \frac{2x \, dx}{\sqrt{x^4+25}}$. This integral can be solved using the substitution method, but we will use the table of integrals to find a more elegant solution.

The Table of Integrals

The table of integrals is a collection of known integrals that can be used to solve a wide range of problems. It is a powerful tool that can be used to evaluate integrals that would be difficult or impossible to solve using other methods. The table of integrals is typically organized by type of integral, with each entry corresponding to a specific type of integral.

The Integral to be Evaluated

The integral we will be evaluating is $\int \frac{2x \, dx}{\sqrt{x^4+25}}$. This integral can be written in the form $\int \frac{2x \, dx}{\sqrt{x^4+a^2}}$, where $a$ is a constant. In this case, $a=5$.

Using the Table of Integrals

To evaluate the integral, we will use the table of integrals. The table of integrals states that $\int \frac{x \, dx}{\sqrt{x^2+a^2}} = \sqrt{x^2+a^2} + C$. We can use this result to evaluate our integral.

Substitution Method

To evaluate the integral, we will use the substitution method. We will substitute $u=x^2+25$ and $du=2x \, dx$. This will allow us to rewrite the integral in terms of $u$.

Evaluating the Integral

Using the substitution method, we can rewrite the integral as $\int \frac{1}{\sqrt{u}} \, du$. This is a standard integral that can be evaluated using the power rule of integration.

Solving for the Integral

To solve for the integral, we will integrate the expression $\frac{1}{\sqrt{u}}$. This will give us $\int \frac{1}{\sqrt{u}} \, du = 2\sqrt{u} + C$.

Substituting Back

To find the final answer, we will substitute back $u=x^2+25$. This will give us $2\sqrt{x^2+25} + C$.

Conclusion

In this article, we used the table of integrals to evaluate the integral $\int \frac{2x \, dx}{\sqrt{x^4+25}}$. We also used the substitution method to evaluate the integral. The final answer is $2\sqrt{x^2+25} + C$.
