TL;DR: If f is differentiable at a point z0, then there's the linear function (Df)(z0): C → C; z ↦ f ′ (z0)z that approximates f well around z0. Multiplication by a complex number is a rotation or a scaling of the complex plane, thus it keeps orientation. These imply that f has to keep orientation locally, around z0. Answer: It is read as z bar. Thus, z bar means the conjugative of the complex number denoted by. We can write the conjugate of complex numbers just by changing the sign before the imaginary part of the complex number. When is purely real, then z bar equals z. When z is purely imaginary, then z + z bar equals 0.

You can treat i as any constant like C. So the derivative of i would be 0. However, when dealing with complex numbers, we must be careful with what we can say about functions, derivatives and integrals. Take a function f(z), where z is a complex number (that is, f has a complex domain). Then the derivative of f is defined in a similar manner to the real case: f^prime(z) = lim_(h to 0) (f(z+h
norm () - It is used to find the norm (absolute value) of the complex number. If z = x + iy is a complex number with real part x and imaginary part y, the complex conjugate of z is defined as z' (z bar) = x - iy, and the absolute value, also called the norm, of z is defined as : CPP. #include . #include .

So this is the conjugate of z. So just to visualize it, a conjugate of a complex number is really the mirror image of that complex number reflected over the x-axis. You can imagine if this was a pool of water, we're seeing its reflection over here. And so we can actually look at this to visually add the complex number and its conjugate.
