Homework Statement
Show that sin(z) satisfies the condition. (Stated in the title)
Homework Equations
The Attempt at a Solution
f(z) = sin (z)
= sin (x + iy)
= sin x cosh y + i cos x sinh y
thus,
u(x,y)=sin x cosh y ... v(x,y)= cos x sinh y
du/dx = cos x ... dv/dx = -sin x
du/dy = -sinh y ... dv/dy = cosh y
therefore I will compare it with the Cauchy Riemann formula.
Am I right to say it doesn't satisfies the condition??
