Math Question

[geoschmo]

Ok, so my problem was simple I guess. I forgot the true mathematical definition of square root. I thought that the sqrt(x²)=x, but that is incorrect. Actually the sqrt(x²)=|x|

You guys in five short Posts or so just totally ruined any desire I might have had to return to school.

Atrocities, you are killing me old boy. Wait for me to get my hands on a camera and I'll show you the most painful math you will ever see.

(I will be back with a picture in a few days; I promise you)

I might have to take another look at my math books to be able to do trig again, but from what I remember about trig and algebra they were easier when I went back to school to get my degree.

Should I post some of my old calc homework and really kill any desire?

Or maybe some statatics..

SD = sqrt((sum of y deviations - y average)^2)/n)

You mean kind like...

[(d^2)z/(dt)^2] + [k/m*z] - [kL/m] + [C/m(dz/dt)] - [g] = [kA/m*sin(wt)]

I have a test involving this problem in about an hour and a half.

Yep. Fortunately I didn't have to get too deep into calc for my major..even the course I took was a pain.
