Complex analysis equations

What are the equations of complex analysis?
The amplitude or argument of a complex number z = x + iy is given by: arg(z) = θ = tan^-¹(y/x), where x, y ≠ 0.
Also, the arg(z) is called the principal argument when it satisfies the inequality -π \x26lt; θ ≤ π, and it is denoted by Arg(z)..

What is CR equation in complex analysis?
In the field of complex analysis in mathematics, the Cauchy–Riemann equations, named after Augustin Cauchy and Bernhard Riemann, consist of a system of two partial differential equations which form a necessary and sufficient condition for a complex function of a complex variable to be complex differentiable..
What is the algebra of complex analysis?
The algebra of complex numbers (complex analysis) uses the complex variable z to represent a number of the form a + bi.
The modulus of z is its absolute value..
What is the equation for a complex function?
A complex function is not so easy to plot: every complex value z=x+jy is mapped to a new value f(z)=x′+jy′ where x′=fr(x,y) and y′=fi(x,y).
In terms of real valued functions a complex function is the combination of two real valued functions in two variables..
Why is complex analysis nicer than real analysis?
I think one reason Complex Analysis is so nice is because being holomorphic/analytic is an extremely strong condition.
As opposed to real analysis, differentiability is a rather weak condition, so we have functions that are differentiable once but not twice etc._{Apr 27, 2016}.

In terms of real valued functions a complex function is the combination of two real valued functions in two variables.
It can be used to provide a natural and short proof for the fundamental theorem of algebra which states that the field of complex numbers is algebraically closed.
If a function is holomorphic throughout a connected domain then its values are fully determined by its values on any smaller subdomain.
The definition of a complex analytic function is obtained by replacing, in the definitions above, "real" with "complex" and "real line" with "complex plane".
A function is complex analytic if and only if it is holomorphic i.e. it is complex differentiable.

A fundamental result of complex analysis is the Cauchy-Riemann equations, which give the conditions a function must satisfy in order for a complex generalization of the derivative, the so-called complex derivative, to exist. When the complex derivative is defined "everywhere," the function is said to be analytic.
