The math problem thread

[Indy Coug]

I've got and easy one for you math geeks. Solve: Ax + By = Cz. And oh btw, it is worth a cool million for you.

Pythagoras just shat his tunic.

My turn to toss one out (so to speak):

All good snowball fighters know that a fun way to hit your opponent is to throw one snowball in a high arc with a dramatic windup. Then while he/she is distracted watching that snowball, you sneak in a second one on a more direct line.

Suppose you throw the first snowball at a velocity of 25.3 m/s and at an angle of 68.4 degrees. How many seconds should you wait after throwing the first one and what trajectory (angle) should you use on the second snowball, assuming it is thrown with the same velocity?

Why would I waste a throw like that? I'd rather put one right in the face of the other guy and while he's stunned from the direct shot, immediately put another in his face and another and another and another, until he finally falls down.

I'll probably spend more time on the link at the bottom of that article:

48/2(9+3) = ?

There is a single, unambiguous answer to this problem. However, it's been posted on several internet fora in the last couple days, and every time it becomes the subject of intense debate. Let's see if CUF can be the first to just get it right.

Yeah, I know I'm late, but this was a welcome diversion. A computer would parse this as the expression tree below, then evaluate the expression tree with a depth first traversal. This tree is directly translated to reverse polish as "9 3 + 48 2 / *".

If I were doing on my HP48, I would do

48 2 / 9 3 + *

48 2 / 9 3 + *

Yeah, the order of the left and right subtrees don't matter, but a compiler would parse the expression in the parentheses to be in the left subtree.
