CAUCHY - RIEMANN Hep please

[timeforchg]

Why did Cauchy - Riemann invented this??? arrgghh help please.

Show that sin(z) satisfies the CAUCHY - RIEMANN conditions for analyticity for all values of z. Does [1/sin(z)] satisfy similar conditions? Calculate the derivative of [1/sin(z)] at z=0,

. Comment on each answer.

Do you know the definition of Cauchy-Riemann condition for analytic functions?

Do you know the definition of analytic functions?

Please share your work with us, indicating exactly where you are stuck - so that we may know where to begin to help you.
