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.

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
