Graphical representation of Interpolation and Extrapolation In this post we define some definitions of numerical analysis and their formulas which are very important related to the topic.There are seven types of it. Definition:(Interpolation)             The process of finding the value of function inside the given range of arguments is known as interpolation Definition:(Extrapolation)     …

Locus of complex number play a very important role in the complex analysis. Today we learn how to represent and find the locus of a complex number. We can also prepare Multiple choice questions about this topic and complex analysis.          Let  P(Z) be the property that satisfied by a complex number  z = x + iy. …

  Modulus:    It is defined as                        Argument: Arg(Z):  It is defined as                        it is also known as amplitude of Z    symbolically amp(Z) Note:  If |Z|=0 then x=0 and y=0 The Argument θ of a complex number is …

The polar coordinates of a P are (r,θ) where r is known as modulus and  θ is the argument of a complex number Z. From above figure   a   =   r cosθ  b   =   r sinθ or  The plane is known as Argand plane or Argand Diagram or complex plane or Gaussian plane.

Let      Z1=( x1, y1 ) =             Addition:  The sum of two complex numbers is                                                                                   Subtraction:  The …

Need Of Complex Numbers Some quadratic equations which have no solutions in real numbers.  For Example 1.     2.    3.    In order to find the solutions of above given or similar quadratic equations, the symbol ” i  ”  was used.  Euler was the first person to introduce the symbol ” i “. where                 …
