I've looked at the unsw website... its not clear thanks

yeap its smooth. some sort of polynomial

its unknown. which is why experiments are needed to determine the relationship.if the relatinoship Q = f (A,B,C) was known, we wouldnt need to be doing any experiments.. but to establish the relationship, first we need to set up the experiment itself. this is where i need to know how to set...

experimentally, by performing some tests. SHould i see what the optimum ratio of A:B is (ie find the ratio of A:B for which Q is optimised) and then take that blend of A & B and do the following: A&B : C 1: 0 0.8: 0.2 0.6: 0.4 0.4: 0.6 0.2: 0.8 0: 1 and take the optimum of that as...

If I have 2 variables, A and B (A+B = 1), and i wanted to see the effect of varying these two on a quantity Q then i could just do an experiment where i go: A: B 1: 0 0.8: 0.2 0.6: 0.4 0.4: 0.6 0.2: 0.8 0: 1 and measure Q for each ratio (and choose the ratio which gives the best Q). But...

Whats the best way to back up important documents?
