English: An image showing the trigonometric functions on 2d space:
Blue - Sine
Green - Cosine
Red - Tangent
Blue (dotted) - Cosecant
Green (dotted) - Secant
Red (dotted) - 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
</source>
then I heavily post-processed with Inkscape.
