Integrate the cosine of an exponential expression

The video tutorial covers the substitution method in calculus, focusing on the chain rule for differentiation. It begins with an introduction to substitution, followed by a detailed explanation of the chain rule. The instructor demonstrates how to apply the chain rule in solving calculus problems, emphasizing the importance of understanding the derivative of the inside function. The tutorial concludes with an integration example using substitution, reinforcing the concepts discussed.
