poles and singularites?

whats the difference between poles and singularites?

Yeah got a math final in a couple of hrs - pretty much fucked - any help?

you get pairs of poles, and you get single singularities.

A pole is a type of singularity. The nicest type.

∫Sin[Log[x]] dx = ∫x*Sin[u] du where u = Log[x]

well, u=Log[x] which makes du=(1/x)dx

then this would require that dx = x du

Since the substitution is off by more than a constant (a variable) you can't do this integral by simle substitution. fail.

apart from the fact you answered this in the wrong thread;

doesn't the x just after the summation at the beginning of ∫x*Sin[u] du count?

epic fail

.... 4chan is this the best moots can do?

I'd say a pole is the second nicest type.

In any case it's agreed: poles are pretty nice as singularities go!
