any math experts here???

[Mday]

i mean like ppl that know more than me that is...

i need to see how some graphs look...

w = f(z) = cos(z) st z is in C, the field of complex numbers.

for all z in the form of: x+iy (i being the algebraic number not in R), where x is held constant or y is held constant (for any given z)... for a few simple values (integers are fine) of x and y.

i have the obvious map where y is 0 and x is arbitrary.

i suppose i should use the complex exponential definition cos...

i used the complex exponential def, and wrote cosz in terms of coshiz and then in terms of cosx, sinx, coshy and sinhy which made a nice parametric equation for myself... =D

sigh... doing math half asleep and half hungry is not fun...

thanks for the help ppl...
