Ok, so you know in math you do all of these "application" problems where they say, "If you know the trajectory of a ball is given by this equation, after how long will it hit the ground?" or something like that? Where do the equations come from?! If we are really supposed to be applying stuff, we should know how to make these equations! It's not like you walk around every day and see a bird flying and know, "Well it's flying northwest in a parabolic pattern at a speed of 10 mph, so I know that in X seconds it will be directly above my head." Equations aren't just handed out to you! So where do they come from and why hasn't anyone taught this to me? That would be the really useful thing to know how to do. Who cares if you can solve an equation if there's no equation given to you from your loving texting book to solve?
This has bothered me off and on since high school. I just really needed to let it out. :P
