| Which one is Newton? |
What is the difference between a differential in calculus and one in life? Is there a calculus of life? "Calculus" is derived from the Latin for pebble. A differential is thus a small change, but it can also be employed to describe any method of reasoning or figuring things out for example in the citation of an "ethical calculus" or "political calculus." "Algebra" by the way, derives from the Arabic al-jabr, "the reunion of broken parts." One of the simplest examples of a differential is finding the area of a square when one of its side lengths increases by a small amount. In lay terms it's tipping the boat. You are living together happily, but one of you gets a new job which involves travel. It's a no brainer, If A represents an unchanging relationship with the same amount of distance on each side. Then. A squared represents the space. Sometimes people need space, but instead of having to run just go, dA=2x.dx. Why spend money on a therapist when it's a D.I.Y situation, best handled on the abacus at home? Of course, differentiation is what makes for horse races. If you can't differentiate between what's important and minor then join 'em!
