^ True, true.

(The thing is, most people know what irrational numbers are. Not everyone I know know what transcendental numbers are, for example.)

I knew that irrational numbers cannot be described by simple fractions, but I didn't know about the "cannot be represented as a decimal" part either. I always associated transcendental numbers with that latter part xD


Here's a problem...
[FLEFT][/FLEFT] In the setup shown, S is a length of cord 30'' long, and L is a rod of 20'' long. L also weighs 10 pounds. The whole entire system next to the wall is at rest.

Find the tension in S and the length h.











This is seriously all that is given.
