Problem 2: Given a complex number

z=x+iy

in rectangular form, we define

e^(z)

to be

e^(z)=e^(x)e^(iy)

, and recall that

e^(iy)

was previously defined through Euler's formula. (a) Write the function

f(z)=e^(z)

as

f(z)=u(x,y)+iv(x,y)

. (b) Use your answer to part (a) to show that

\lim_(z->2+i\pi )e^(z)=e^(2+i\pi )

.
