Oh yeah, I'm saying this because I'm seriously getting irritated with my Chemistry teacher and his lack of good judgement. I would have liked to restrain myself with that but look at this: Imagine you do an experiment. There's an equation that goes A= e.l.c. You don't have the e or the l, those we'll group and make it this way: A=k.c. being the k= e.l., a constant since both e and l are. This gives a linear equation, A/c= k. Then, I want to know the c' for a certain A'. I have the A' but don't have the c', and so, I previously made several experimental values to get a approximated value of k which I calculated, using the calculator, giving an equation of the linear equation that best adjusted to it. I had now the incognit k that I needed. We traced a graphic of the line using paper and wrote in the legend the linear equation we got from the calculator.
Then, when I receive my report of the work, I see a note saying I should have compared the calculated one with the graphic one. (frown) What the hell, it's the same one! I tried to call him to his senses, but he keep insisting it was a different thing and so on. The only thing he could have asked me was the theoric value, but for that he had to give me the value of k (or atleast the e, as I knew the l already). But he didn't. So, no sir, you are wrong.
Does anyone encounters such things as this? Feel free to curse away.
