The choice of u and v in the integration by parts technique is significant. We selected u to be x because then du will be 1 dx, thereby simplifying the integral. If we had instead selected u = cos x and dv = x dx then we would have found that v = x 2 /2 and du = sin x dx and the new integral v du = is more complicated.

When should I use exception handling in a program When should I create my own custom exception classes Since C# extensively uses exceptions to report errors, nearly all real-world programs will make use of exception handling. This is the part of exception handling that most new C# programmers find easy. It is harder to decide when and how to use your own custommade exceptions. In general, there are two ways errors can be reported: return values and exceptions. When is one approach better than the other Simply put, in C#, exception handling should be the norm. Certainly, returning an error code is a valid alternative in some cases, but exceptions provide a more powerful, structured way to handle errors. They are the way professional C# programmers handle errors in their code.
