of the Trigonometric Functions - Given at least one side
and one other side or angle of a right triangle, the other six
sides and angles can be determined using the trigonometric functions.
Also contains info on vectors and graphs of trig functions.

- http://library.advanced.org/10030/4vectors.htm Vectors - A vector is a quantity that has both direction
and magnitude. A vector is denoted by a directed line segment.
The magnitude of a vector is the length of the segment and the
direction of a vector is where the segment is pointing.

that is not a right triangle. It could be an acute triangle
(all three angles of the triangle are less than right angles)
or it could be an obtuse triangle (one of the three angles is
greater than a right angle). Actual

geometry, but the subject of trigonometry is based on the measurement
of angles

with the vertex of an angle at its center, then the measure

the angle.
