So what did you get? Can you show us your code? So we can continue with that instead of beginning from zero.

Code: Select all

\begin{tikzpicture}[x=4cm,y=4cm]
 
\draw[line width=1pt] (0,0) .. controls (0.17,0.67) and (0.83,0.67) .. (1,1); 
 

\node[label={[label distance=0.0cm,text depth=-1ex]left:$\gamma$}] at (-0.1,.8) {};

\end{tikzpicture}

But i am not getting what i want! can you help me in drawing what i want?

Here's a quick drawing of the function image, using nodes and the to operation.

I used relative positions, by changing the values you can tweak the drawing.

Code: Select all

\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{positioning,decorations.markings,quotes}
\begin{document}
\begin{tikzpicture}[
  dot/.style = {circle, draw, fill, inner sep=2pt},
  decoration = {
    markings,
    mark=at position 0.5 with {\pgftransformscale{2}\arrow{stealth}}},
  ]
  \node (gamma-a) [dot,"$\gamma(a)$"] {};
  \node (gamma-b) [above right = 1cm   and 4 cm of gamma-a,
                   dot,"$\gamma(b)$"] {};
  \node (below)   [below right = 0.5cm and 1 cm of gamma-a] {};
  \node (above)   [above left  = 0.5cm and 1 cm of gamma-b] {};
  \draw [postaction={decorate}] (gamma-a)
    to [out=0, in=180] (below)
    to [out=0, in=180] (above)
    to [out=0, in=180] (gamma-b);
  \node (gamma-t) [below left  = 0.1cm and 2.2 cm of gamma-b]
    {$\gamma(t)$};
\end{tikzpicture}
\end{document}

i am getting a error for \usetikzlibrary{positioning,decorations.markings,quotes}
can't find

[Stefan Kottwitz]

What is the exact error message?

Do you know which version of TikZ you are using? It should be at least TikZ 3. If it's older, I recommend to update, since TikZ has been improved a lot.
