RECENTLY ON TOL:
- A tumblr site dedicated to the people and places that make up Oregon and Southwest Washington.
on Math Appeal
OK I know the people on the show know this:
It is all Calculus!!!!
Geomotry, area, slope of curves (trig) are all calculus you just remember the short cut 4/3*Pi*r^3 not understanding that that is an integral of the area of a circle.
Stats and probability: Calculus, You just forget that you are finding the area under that probability to give you your chance.
Physics, engineering, all the sciences: D=V*T integrates to D=V0T+.5at^2 to allow you to calulate speed. Electronics L R C is the perfect model for a diff eq.
Finance: A= Pe^(rt) (continuous compunding interest) Is a diff eq. of course the banks would rather compund interest you owe this way and interest they owe at a rate less than this as it makes them money.
Distince = Rate x time
d=Vi *t + .5*a*t^2
(Distance with acceleration)
Force = Mass x Acceleration
but what if the mass is alrady traveling at 200 miles an hour does it not add to the force? Well we have forgot that this too is a diff eq and a more complete formula is (looking a lot like distance):
F= Ma + .5Mv^2
