Complex Analysis-Mathematica

Practical 1 : Declaring complex numbers e.g. z1=3+4i, z2=4-7i. Discussing their algebra z1+z2, z1-z2, z1*z2 and z1/z2 and the plotting them.

Practical 2 : Finding conjugate, modulus and phase angle of an array of complex numbers, e.g. Z={2+3i, 4-2i, 6+11i, 2-5i} and plotting them for a complex number.



Practical 3 : Compute the integral of a complex function over a straight line path between the two specified end points as a+ib and c+id.



Practical 4 : Perform contour integration for complex function with contour C, which is given by g(x,y)=0.



Practical 5 : Plotting of the complex function, e.g. f(z)=z^3.

Program 6 : Finding the residue of complex functions.




Program 7 : Taylor series expansion of a given function f(z) around a given point z, given the number of terms in the Taylor series expansion. Hence comparing the function and it's Taylor series expansion by plotting the magnitude of each.






Program 8Laurent series expansion of a given complex function f(z) around a given point z.
(i) f(z)=(Sin(z)-1)/z^4 around z=0,
(ii) f(z)=Cot(z)/z^4 around z=0, etc.





















Program 9: Computing of Fourier series, Fourier sine series and Fourier cosine series of a complex function and plotting their graphs such as f(z)= z^2.
