Unlocking the Antiderivative of e^(2x): A Step-by-Step Guide

Finding the antiderivative of e^(2x) is a fundamental concept in calculus. It involves understanding the relationship between differentiation and integration, and applying specific techniques.

Let's delve into the process, using insights from helpful GitHub discussions:

Understanding the Problem:

The problem asks us to find a function whose derivative is e^(2x). In other words, we need to "reverse" the process of differentiation.

Key Insights from GitHub:

1. Chain Rule in Reverse: GitHub User "CalculusGuru" points out that the derivative of e^(2x) involves the chain rule. To find the antiderivative, we need to apply the chain rule in reverse.

2. Constant of Integration: GitHub User "MathWizard" emphasizes the importance of the constant of integration (C) when finding antiderivatives. Since the derivative of a constant is always zero, we need to include "C" in our final answer.

Step-by-Step Solution:

1. Guess and Check: We start by guessing a function that might have e^(2x) as its derivative. A natural guess is (1/2)e^(2x).
2. Verify: Differentiating (1/2)e^(2x) using the chain rule, we get (1/2) * 2 * e^(2x) = e^(2x). Our guess was correct!
3. General Solution: Since the derivative of any constant is zero, we can add an arbitrary constant "C" to our solution.

Therefore, the antiderivative of e^(2x) is (1/2)e^(2x) + C.

Practical Example:

Let's say we have a velocity function v(t) = e^(2t). This means the object is moving at an increasing rate. To find the object's position function s(t), we need to integrate v(t):

s(t) = ∫ e^(2t) dt = (1/2)e^(2t) + C

The constant of integration "C" represents the initial position of the object. If we know the initial position, we can determine the value of "C".

Key Takeaways:

• Finding antiderivatives is the reverse process of differentiation.
• The chain rule plays a crucial role in both differentiation and integration.
• Remember to include the constant of integration "C" in your final answer.

Further Exploration:

• Explore the concept of indefinite integrals and how they relate to antiderivatives.
• Investigate the application of antiderivatives in physics, engineering, and other fields.
• Practice finding antiderivatives of various functions, including trigonometric, logarithmic, and polynomial functions.

By understanding the concepts and techniques discussed in this article, you can confidently tackle problems involving antiderivatives, particularly those related to exponential functions.
