1년 전에 배운 문제를 다시 보니 전혀 풀 수 없어서 챗GPT에 물어봤다. 나: 적분을 구하시오. \[ \int x e^x dx \] 챗GPT: To solve the integral\[ \int x e^x dx \]we can use the method of integration by parts. This technique is useful when the integrand can be decomposed into a product of functions, where one function is easy to differentiate and the other is easy to integrate. Let's denote:\[ u = x, \quad dv = e^x dx \]Differentiating ..
