The exponential function e x is just vibing in its own mathematical universe! No matter what operation you throw at it—differentiate it, integrate it—it just stays e x , completely unbothered. It's the mathematical equivalent of that friend who never changes despite life's chaos. While other functions are having identity crises when differentiated, e x is just like "I'm still me, bro!" The ultimate mathematical narcissist—always returning to itself. Even calculus can't mess with its perfect mathematical zen!
