The image of the imaginary axis under z ↦ iz z ↦ i z. Example 1.8.1 1.8. 1. The mapping w = z2 w = z 2. We visualize this by putting the z z -plane on the left and the w w -plane on the right. We then draw various curves and regions in the z z -plane and the corresponding image under z2 z 2 in the w w -plane.
1. Cauchy-Riemann equations. Remembering that z = x+iy and w = u+iv we note that there is a very useful test to determine whether a function w = f(z) is analytic at a point. This is provided by the Cauchy-Riemann equations. These state that w = f(z) is differentiable at a point z = z0 if, and only if, ∂u ∂v ∂u ∂v.
Putting all the results together, the complex exponential function is found to be. (z) = ez = ex cos y + iex sin y, By setting. x = 0, we then deduce the Euler formula: eiy = cos y + i sin y. It can be verified that. ez1+z2 = ez1ez2, another basic property of the exponential function.
If u=f(e(y-z),e(z-x),e(x-y)) then \[Prove \ that = \dfrac{{\partial}u}{{\partial}x}+\dfrac{{\partial}u}{{\partial}y}+\dfrac{{\partial}u}{{\partial}z} =0\]
