In summary, an integral is difficult to solve if it cannot be expressed in terms of elementary functions, such as polynomials, trigonometric functions, or exponentials. One way to identify a difficult integral is to look for complicated expressions, such as high powers, nested functions, or irrational numbers. There are several strategies for solving difficult integrals, including using integration by parts, partial fractions, trigonometric substitutions, and numerical methods. Computer programs can also solve difficult integrals, but the solutions may not be exact. There is no definitive "most difficult" integral to solve, as it can depend on various factors. However, some commonly challenging integrals include the Gaussian integral, the Fresnel integral, and the elliptic integral.

stupid question!
1. What makes an integral difficult to solve?
An integral is difficult to solve if it cannot be expressed in terms of elementary functions, such as polynomials, trigonometric functions, or exponentials. In other words, there is no simple formula or method to solve it.
2. How can I identify a difficult integral?
One way to identify a difficult integral is to look for complicated expressions, such as high powers, nested functions, or irrational numbers. Additionally, if the integrand (the function being integrated) is not a well-known function, the integral may be difficult to solve.
3. Are there any strategies for solving difficult integrals?
Yes, there are several strategies for solving difficult integrals. These include using integration by parts, partial fractions, trigonometric substitutions, and other advanced techniques. Additionally, numerical methods, such as the trapezoidal rule or Simpson's rule, can be used to approximate the value of the integral.
4. Can computer programs solve difficult integrals?
Yes, computer programs can solve difficult integrals using numerical methods or advanced algorithms. However, it is important to note that these solutions may not be exact and may require additional verification.
5. Is there a most difficult integral to solve?
It is difficult to determine a single most difficult integral to solve as it can depend on various factors, such as the chosen method of integration, the complexity of the integrand, and the limitations of the computer or software being used. However, some integrals that are often considered very difficult to solve include the Gaussian integral, the Fresnel integral, and the elliptic integral.
