OH this is too good!

Subtitle, why Mom homeschools.

sounds like the student could teach the teacher a few things, Pong

Did she tell the kids that their math skills are obsolete, the Excel program can do most of it anyway!

#14.....1 + 1/2 + 1/2 = 2 1/2????

HA!HA!HA! LOL!..and I thought, I was MATH CHALLENGED...in addition to....

..and the Education unions wants MORE $$$$ for MATH & SCIENCE Instructors :)

This kid is a real weirdo.

His home page is here: http://www.willamette.edu/~jtdavis/

There's some really bizarre stuff here: http://www.willamette.edu/~jtdavis/saveusdavis/WARNING.HTML.

Hope he's not in any danger of going postal [or should I say, "columbining"?]...

If only the world wide web had existed when I was a kid - or even when I was at the state university.

My teachers would have actually taught for their pay.

I am of the mind that this must all be true, as it is way to bizarre to be fiction.

This is great! This teacher is either a moron or is having some private fun at the kids expense (having been around high schoolers, the later is something I could envision myself doing).

I used to make snide little notes about teachers I didn't like too. I see now what an ass I was.

...40. Told us that it's possible for a math problem to be its own grandma...

example: if f(x) = cosh(x), what is f'(x)?

this problem produces the answer (daughter) f(x) = sinh(x).

repeating the problem using the daughter function you get: if f(x) = sinh(x), what is f'(x)?

this daughter problem produces the answer (granddaughter) if f(x) = cosh(x), what is f'(x)?, which is the original problem (so grandma = granddaughter).

makes sense to me. I think this guy should spend more time trying to learn math rather than trying to prove his teacher knows nothing.

also, using sound waves are sine waves, so showing how, say 3sin(x) sounds different than sin(3x) is a good way to learn what they are. (in my example, the 3sin(x) would be much higher pitched and three times as loud as the sin(3x).

My son came home late once from shop class (the only class he took in the public school) because he was engaged in a debate with the "teacher" who was explaining the use of the "4, 5, 6" triangle to construct right angles.

When my son and his friend suggested that it should be a "3, 4, 5" triangle, the teacher "corrected" them. He didn't follow their explanation of the Pythagorean theorem, and said that his lesson had nothing to do with that.

BTW, shop is not this teacher's area of expertise. He is really a math teacher. Honest.
