In an earlier post, the enjoyment of knowing maths was demonstrated in its ability to form pictures.
Here is another example of playing with the trigonometry to create mathematical art.
In this piece of art, 4 graphs of various mathematical expressions were overlapped to form the result.
I name this piece of art the "Lines of Wisdom".
In the graphs, maths functions like the sine and sinh operation were used together with trigonometrical multiplication.
