Hvala.
Koristio sam PGF/TikZ, kod se kuca u LaTeX-u, pocetnik sam i nisam mnogo vešt (sto ce se videti i iz koda). Evo i koda:
Code:
\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{calc,decorations.markings}
\begin{document}
\begin{tikzpicture}
% Configurable parameters
\def\gap{0.2}
\def\bigradius{3}
\def\littleradius{0.5}
% Axes
\draw [help lines,->] (-1.25*\bigradius, 0) -- (1.25*\bigradius,0);
\draw [help lines,->] (0, -1.25*\bigradius) -- (0, 1.25*\bigradius);
% Red path
\draw[fill=orange!50,line width=1pt, decoration={ markings,

Leonardo da Vinči
Nema istine u onim naukama u kojima se matematika ne primenjuje.
Milorad Stevanović
Bog postoji zato sto je matematika neprotivurečna.
Integral iz realnih i kompleksnih funkcija
