What is the best way to approach an integral of an exponential function with a complex exponent?

+
When dealing with a complex exponent, it’s crucial to simplify the expression first. Try to express the exponent in terms of simpler functions, such as trigonometric or logarithmic functions. This simplification often leads to a more manageable integral.
Are there any specific integration techniques for integrals involving ex and 2x?

+
Yes, there are specific techniques for these common integrals. For ∫ex dx, the solution is ex + C, where C is the constant of integration. For ∫2x dx, the solution is 2x / ln(2) + C. Practice these integrals to memorize the solutions and improve your speed.
How can I check the accuracy of my solution for an integral of an exponential function?

+
To verify your solution, differentiate your answer. The derivative of the integral should match the original function. Additionally, you can compare your solution with the solutions provided in textbooks or online resources to ensure accuracy.
What are some common mistakes to avoid when solving integrals of exponential functions?

+
Common mistakes include forgetting the constant of integration, misapplying integration techniques, and not simplifying the final answer. Always double-check your work, and ensure you understand the properties of exponential functions to avoid these pitfalls.
