Graphics, Figures & Tables ⇒ Smooth Curve for Sine Function

[coachbennett1981]

Good morning from the District of Columbia!!! I plotted the following function, but the line is not a smooth curve. Does anyone have suggestions on how to fix this problem?

Code: Select all

\psset{trigLabels=true,labelFontSize=\scriptstyle,xunit=\pstRadUnit}
\begin{pspicture}(-\psPiTwo,-4)(10,4)
\psaxes[trigLabelBase=2]{<->}(0,0)(-\psPiTwo,-5)(\psPiTwo,5)
\psplot[xunit=1cm,linecolor=red,linewidth=1.5pt]{-\psPiTwo}{\psPiTwo}{x 2 mul 3.14159265 add RadtoDeg cos 2 mul 2 sub}

Best,

Nick

Ever heard of the plotpoints option for the graphics commands? If not, search the PSTricks manual.
