Best exemplified by x^x. Differentiation is tricky but doable. Integration is impossible.
- AnimalMuppet 5y agoDepends on your definition of "impossible" ;-) In high school, I transformed x^x into e^(x log x), expanded that into the Taylor series, and integrated term by term. I got a "solution", but it wasn't closed form - it was an infinite series. And, for a given error limit, it probably converged more slowly than a decent numerical integration. So, not worth much. But I "solved" it...
