Graphics, Figures & Tables ⇒ Cosecant and Secant functions

[coachbennett1981]

Does anyone know code to plot these functions. I have tried the following and get a fail message for an output:

Code: Select all

\begin{pspicture}(11,-2)(-3.5,8)
\psaxes[labels=none,ticks=none,trigLabelBase=2,dx=\psPiH, xunit=\psPi,trigLabels,linewidth=1.5pt]{<->}(0,0)(-2,-3)(3,4)[$x$,0][$y$,90]
\psplot[linestyle=dashed,yMaxValue=4,linewidth=1.5pt,plotpoints=2000,linecolor=red]{-1.56}{1.56}{1/sin(x)} 
\psset{algebraic}
\end{pspicture}

I have changed the domain values in case there was a problem with the asymptotes. I also tried using.

Code: Select all

csc(x)

in place of 1/sin(x).


Here is the code for my document.

Code: Select all

Thank you for your time.

I used the following code:

Code: Select all

\begin{pspicture}(-0.5,-3)(6.5,4)
\psaxes[trigLabelBase=2,dx=\psPiH, xunit=\psPi,trigLabels]{->}(0,0)(-3,-3)(3.7,4)[$x$,0][$y$,90]
\psset{algebraic}
\psplot[linewidth=1.6pt,plotpoints=2000,linecolor=red,arrows=<->]{-8}{9.42}{sin(x)}
\psplot[linewidth=1.6pt,plotpoints=2000,linecolor=blue,arrows=<->]{-8}{9.42}{1/sin(x)}
\end{pspicture}

is there a way to get rid of the asymptote lines?
