1. hi there I am a bit confused, I am doing a survey of 100 respondents. ive asked them 5 colors to choose from ( red, green, blue, yellow and black) ive got these results from my survey of 100 respondents red = 21 green = 36 blue = 19 yellow = 10 black = 142. is my sample size 100? or 5? how...

ok great tnhks

ok so d/dx (ln e) = 1 not "0"? if it is 1 then d/dx 1 = 0 ; where d/dx c = 0

derivative of x^x = x^x ln x (y'/y) = [ (x^x) . (ln e) ] (y'/y) = [(x^x ln x) (ln e)] + [(x^x) (1/e) (e.0)] <-- is this right d/dx of (ln e) is 0?

please enlighten me, what is the derivative of (ln e) ; natural log e is it 0 or 1? i have this problem in the book y = e^(x^x) and the ANSWER is y' = (x^x) e^(x^x) [1 + lnx] my FIRST solution and i assumed (ln e=1) ; i treated it a constant so it must be "0" where (d/dx) c = 0...

great! thnks

i find it puzzling how to solve this,,. (2)^1/6 or (20)^1/8 without a calculator

great,, i like to hear your conjenctures.. keep it up. Einstein was been disregarded by his colleagues on his theories but he was right after all.

I heard that space itself is the gravity that pushes us down, heavy mass such as the sun warped space, and planets orbit the sun

environmental aspects may also have a great impact becoming an exceptional individual in any fields .(math,science,music etc.)

im 29 first year EE student, for a long time i did not exercise my math because of my work,, after i decided to leave my old life and saved money to finish my studies,. for awhile i left my interest in physics and came back again to awake the sleeping passion in me, i started at square one...

do the basics and master it, exercise a lot, have a passion or desire or love for it.
