I'm not sure what yo0u mean by this. Obviously, . By the "triangle inequality", (equality may apply but doesn't have to) and then is strictly less than because each such was between L-1 and L+1.Also, is the inequality with the equal sign combined technically equal in this case?
The "triangle inequality" applies to positive numbers. The lengths of the sides of a triangle are positive numbers, after all.]As for the triangle inequality itself, does the less than part only or usually apply for the magnitudes of vectors or something?
Any help would be greatly appreciated!
Thanks in advance!
