what is an integral of sin(x)/x
I'm not sure about your sneer (next note down.) I didn't say anything about my academic credentials. Iron did.
You must be an engineer mietla -- only an engineer would ask something like the above in an attempt to discover if someone is a mathematician. Your question is sort of like asking a physician "what are the best nail clippers."
The answer is there is no answer in closed form. You can approximate the answer using a Taylor series. Sometimes the approximation is called "Si(x.)" I guess you know the approximation, so there's no need for me to write it here. Just take the Taylor series for sin(x), divide it term by term by x and then integrate each part of the sum.
Tell ya what, mietla. Let's agree not call me Mr Phd and I won't call you an extrahunk, how's that? Seriously, if you want to continue the testing, do it through private e-mail.
