My tip is to write on your lecture slides directly - this gives your notes some context so when you look back you know what you were thinking about when you wrote those notes. I annotate them on the ipad - you could print them out maybe 4 to a page or something if you prefer. Then during your...

I'm a bit late to the party. I found CHEM1101 hard, and I was incredibly stressed for the exam as well, so I didn't perform as well as I should have. I attempted almost all of the questions, but skipped almost 2 full pages at the end of the test (there was something like 29 pages though). I...

I'm doing advanced biology units this year and I'm nervous as heck about it, but I think it was the right choice. If you enjoy it and want to work hard, go for it. But I think you HAVE to be interested in the subject or the classes will be a real drag. Whilst I think the course would be more...

are you using calculus? the first derivative gives a function of velocity and the second derivative gives a function of acceleration. When f'(x) = 0, the particle is at rest. When f'(x) is >0, the curve is increasing. When it is <0, it is decreasing. When f''(x) = 0, there is potentially a...

Hi guys, I have another one - 3e^3t = 9 ? I end up with 3t = ln3. Is that correct? And t = ln3/3?

Sketch the two curves and look at the graph between the two points you are trying to find the area between.. Whichever one is higher up on the y axis is the one you want to write first, then subtract the other curve which will be lower on the y axis.

right, ok. That kind of makes sense, I guess it's just one of those processes I have to remember. Thank you. There will be more! I haven't had proper teaching on this subject unfortunately so it's shaky as hell and I have very limited time to learn it before an exam. When I want to eliminate...

Alright, I give up. What about ln(lnx) = 1?

I've never done a question like this before, but your answer makes sense. Thanks very much. I may (almost certainly) will be back with more questions. Cheers!

I have been struggling with this problem all day. Can anyone walk me through the steps? solve for x: e^x - 2e^-x = 1. Many thanks. I find this topic really tough.

That's what I expected. Thanks a lot for confirming.

Someone put this to me today and it got me thinking. If you put say four different universities in your preferences, do the universities see that whole list and does it affect your attractiveness as a candidate? Is it better to apply for a few different courses at two universities instead of the...

AH! got it. My method was correct but one little slip sent me astray. Now I get x=2 and y=2. YAY.

Just been looking at your result. Thanks very much, I think I was halfway there but just not knowing how to do that last bit. I really appreciate that!!

Can I ask a supplementary question - what does this question mean? I'm having trouble understanding the problem. "Find the point(s) on the graph of y=1/2x^2 at which the normal line passes through the point (4,1)" I've found the slope (derivative) of the tangent to be x, so the slope of the...

Sorry, I should have worded the question more clearly. :-)

thanks for your response, but I'm still not getting the correct answer. The answers are y = 20x+2 and y = -44x + 2. The point (0,2), if I'm understanding the question correctly, is not on the curve. I assume at some point that I solve for x and get two values and end up with two answers, because...
