Homework Statement
Prove that lim_{z -> 1 - i} [x + i(2x+y)] = 1 + i
where z = x + iy
Homework Equations
Prove using definition of complex limit.
The Attempt at a Solution
Start from |x + i(2x + y) - (1 + i)| < epsilon, need to transform LHS to an expression that includes |(x + iy) - (1 - i)|.
|x + i 2x + i y - 1 - i| < epsilon
|(x + iy) + i 2x - 1 - i| < epsilon
