my singular point is 0

if i will do lhopital 4 times on the lmit i will get -sin z/6 =0

which is singular point because the result is constant

so why its a first order pole?

ok now i tried to determine the power of the pole

i did

g(x)=1/f(x)

where x=0

and i got that g'(0)=0/0 which means that its not a first order pole

actualyy i should get zero but i got 0/0

i want to solve it by the derivative way

not by developing into a series - Jul 13th 2010, 04:57 AMmr fantastic
