Cos

Function: cos (<x>) - Cosine.

load (eigen);
 x: matrix ([1, 2, 2, -1], [1, 1, -5, 3], [3, 2, 8, -7]);
 y: gramschmidt (x);
 map (innerproduct, [y[1], y[2], y[3]], [y[2], y[3], y[1]]);
 load (eigen);
 ip (f, g) := integrate (f * g, u, a, b);
 y : gramschmidt ([1, sin(u), cos(u)], ip), a= -%pi/2, b=%pi/2;
 map (ip, [y[1], y[2], y[3]], [y[2], y[3], y[1]]), a= -%pi/2, b=%pi/2;

There are also some inexact matches for cos. Try ?? cos to see them.
