 limit
 The target value that terms in a
sequence of numbers are getting closer to. This limit is not necessarily
ever reached; the numbers in the
sequence eventually get arbitrarily close to the limit.
 line
 A continuous extent of length containing two or more points (cfLines, Rays, and Planes).
 line graph
 A diagram showing a system of connections or interrelations between two or more things
by using lines.
 line segment
 A piece of a line with endpoints at both ends (cfLines, Rays, and Planes).
 line symmetry
 If a figure is divided by a line and both divisions are mirrors of each other, the figure has line symmetry. The line that divides the figure is the line of symmetry.
 linear
 An equation or graph is linear if the graph of an equation is a straight line.
 linear function
 A function of the form
f(x) = mx + b
where m and b are some fixed numbers. The names "m" and "b" are traditional. Functions
of this kind are called "linear" because their graphs are straight lines
(cfLinear Functions).
 logarithm
 The exponent of the power to which a base number must be raised to equal a given number. An example: 2 is the logarithm of 100 to the base 10. One can look at this way: 10 * 10 = 100, which is the same as 10^{2}, and 2 is the exponent referred to above (cfExponents and Logarithms Discussion and Trees as Data Structures Discussion).
