In signal processing, this definition can be used to evaluate the Z-transform of the unit impulse response of a discrete-time causal system.. An important example of the unilateral Z-transform is the probability-generating function, where the component [] is the probability that a discrete random variable takes the value.
This may be verified by factoring X 64 − X over GF(2). The elements of GF(64) are primitive n {\displaystyle n} th roots of unity for some n {\displaystyle n} dividing 63 {\displaystyle 63} . As the 3rd and the 7th roots of unity belong to GF(4) and GF(8) , respectively, the 54 generators are primitive n th roots of unity for some n in {9, 21 ...
A reflection about a line or plane that does not go through the origin is not a linear transformation — it is an affine transformation — as a 4×4 affine transformation matrix, it can be expressed as follows (assuming the normal is a unit vector): [′ ′ ′] = [] [] where = for some point on the plane, or equivalently, + + + =.
Since z = 1 − x, the solution of the hypergeometric equation at x = 1 is the same as the solution for this equation at z = 0. But the solution at z = 0 is identical to the solution we obtained for the point x = 0, if we replace each γ by α + β − γ + 1. Hence, to get the solutions, we just make this substitution in the previous results.

For a meromorphic function, with a finite set of singularities within a positively oriented simple closed curve which does not pass through any singularity, the value of the contour integral is given according to residue theorem, as: = = (,) (,). where (,), the winding number, is if is in the interior of and if not, simplifying to ...
