File:Trigonometric functions.svg

An image showing the trigonometric functions on 2d space: Green - Cosine, Blue - Sine, Red - Tangent, Yellow - Cosecant, Magenta - Secant, Cyan - Cotangent. I created it with the following Gnuplot code:

# set the output
set terminal svg enhanced fname "Times" fsize 18
set output "trigonometric_functions.svg"

# axis properties
set xrange [-1.5*pi:1.5*pi]
set yrange [-3:3]
set grid xtics ytics
set key 7,3

plot sin(x) title "sine" with lines linewidth 2,\
     cos(x) title "cosine" with lines linewidth 2,\
     tan(x) title "tangent" with lines linewidth 2,\
     1/cos(x) title "secant" with lines linewidth 2,\
     1/sin(x) title "cosecant" with lines linewidth 2,\
     1/tan(x) title "cotangent" with lines linewidth 2

then I heavily post-processed with Inkscape.

This vector image was created with gnuplot.
