In mathematics, the trigonometric functions (also called circular functions) are functions of an angle. They are used to relate the angles of a triangle to the lengths of the sides of a triangle. Tr...

In geometry, the tangent line (or simply the tangent ) to a curve at a given point is the straight line that "just touches" the curve at that point (in the sense explained more precisely below). A...

It is possible to define trigonometric functions rigorously using a procedure based upon the addition formula for the tangent function. ... These will be the values of the tangent function at successive bisections of the right angle. We now use our function $s$ to construct other values of the tangent function.
