May someone please provide the pros and cons of these materials, and a brief summary of each would be appreciative. Also is steel strong in compression + tension, or am i mistaken? Reynolds 853 – air hardened heat treated steel Reynolds X100 – aluminium lithium alloy...

my proposal..hmm. By knowing you're behind, you are not on the same level as the rest of your cohort. Therefore you must study twice as hard as everyone, that means if your teacher tells you to do one ex for hw you do two. If you think you can just work at the same pace as everyone else right...

+ or -?

wow at your rep :haha: The dialysis solution has levels of minerals like potassium and calcium that are similar to their natural concentration in healthy blood. For another solute, bicarbonate, dialysis solution level is set at a slightly higher level than in normal blood, to encourage diffusion...

YAYAYAY thanks :) you did minor error though (in bold) damn i subbed in y values instead of x....silly me

hmm lost still... :(

thats trap rule + its f'(X)

whih one do you nee help on he most? first one is comon denomintor with one fraction, then obtain one whole fraction.Aftewards -the oter. 2) is triple simultaneous. simultaneous with one of the eqations to obtain a few pronuemerals then simultaneous with the other. keyboard batts running out....zomg

L = \int_{a}^{b}\sqrt {1+(f'(x))^2} dx is the lenth of the arc of curve y = f(x) between x = a and x = b. Usig Simpson' rule with five function values, estimate the length of the graph y =x^2 between x = 0 and x =2. Answer correcto two dp. thx

lol thanks great help. I tried taking out - 1/2x LOL, wasn't sure what to do.

thanks i was just curious how you do it 4u style. Just wondering now can you do the reverse chain rule with roots? or only with >1 indices

ehh can anyone not do the cheapy method of area of circle? and actually try to integrate it and find the area...will be much appreciated.

I think you're confused with volume rotation. You can find area no matter what axis you are using, it is simply a matter of applying it.

yes i know that but intergrate it i've tried inverse chain rule and still failed miserably gna take a break and see if i can get back to it

working out please

\int_{-3}^{3} \sqrt {9-x^2} dx

evaluate integral between3 and -3 of y = root (9 -x^2) :spzz:

answers would be great

lol this is the copeland engineering report. anyone actually finished it yet? post here :D

LOL i dont think you do 12hours per day on eco. back at home from school = 3.30? 12hrs study = 3.30am LOLOLOL SIFNESS and you say daily, super hyperbole? I attempted timetabling my days, but failed miserably. I have adjusted to something more arbitrary and that is finishing all work before a...
