Understanding the Integration of cos(x)/sin(x) dx: A Step-by-Step Approach

The integration of (frac{cos(x)}{sin(x)}) dx is a common problem in calculus. This article provides a detailed explanation and examples of how to solve this integration step-by-step, along with tips and techniques for effective SEO and content optimization.

1. Introduction to the Problem

The given problem is the integration of (int frac{cos(x)}{sin(x)}) dx. This is a classic example of an integration involving a trigonometric function. To solve it, we can utilize the ‘change of variable’ technique, which simplifies the integration process.

2. Step-by-Step Solution

Let us proceed with the solution step-by-step:

2.1 Substitution Method

Step 1: Let (sin(x)) t. This substitution is made to transform the integrand into a simpler form.

Step 2: Differentiating both sides with respect to (x), we get:

(cos(x) dx dt)

Step 3: Substitute (cos(x) dx dt) and (sin(x)) t in the original integral:

(int frac{cos(x)}{sin(x)} dx int frac{dt}{t})

Step 4: Integrate the new form:

(int frac{dt}{t} ln|t| C)

Step 5: Substitute back (t sin(x)):

(int frac{cos(x)}{sin(x)} dx ln|sin(x)| C)

2.2 Verifying the Solution

To verify the solution, we can differentiate (ln|sin(x)| C) with respect to (x) and check if we obtain back (frac{cos(x)}{sin(x)}):

(frac{d}{dx}left(ln|sin(x)| Cright) frac{cos(x)}{sin(x)})

This confirms that the integration is correct.

3. Optimization Techniques for SEO

For SEO purposes, it is essential to ensure that the content is not only accurate and comprehensive but also optimized for search engines. Here are a few tips to optimize the content:

3.1 Keyword Optimization

Ensure that the key terms such as 'integration', 'trigonometric functions', and 'indefinite integrals' are used strategically throughout the content. This will help search engines understand the context and relevance of the content.
