F Z → Z given by f(x) = x 2 f(2) = 2 2 = 4 and f(– 2) = (– 2) 2 = 4 ∴ f(2) = f(– 2) but 2 ≠ – 2 ∴ f is not injective 2 ∈ Z but there is no x ∈ Z such that 2 = f(x) = x 2 ∴ f is not surjective. If Z ~ N(0, 1), then Z is said to follow a standard normal distribution P(Z < z) is known as the cumulative distribution function of the random variable Z For the standard normal distribution, this is usually denoted by F(z) Normally, you would work out the cdf by doing some integration. @u @y (x;y) = 2xy (x 2 y2.

F(z)dz = X i I C i f(z)dz, (517) where C i is the closed path around one of the mesh elements, since the contribution from the side common to two adjacent subcontours evidently cancels, leaving only the contribution from the exterior boundary Now because f is analytic throughout the region, we may write for small δz. It basically says that as zis varied smoothly, there are no abrupt jumps in the value of f(z).
