Step 1: Identify the function you want to integrate, which is e^x.
Step 2: Recall the rule for integrating e^x, which states that the integral of e^x is e^x itself.
Step 3: Add a constant of integration, C, to the result because indefinite integrals have an arbitrary constant.
Step 4: Write the final answer as e^x + C.
Integration of Exponential Functions – The integral of the exponential function e^x is a fundamental concept in calculus, where the result is the same function plus a constant of integration.
