x= 1/3ln(1/2)
x= 1/3ln(2^-1)

1/3ln1/2 = 1/3 ( ln 1 - ln 2 )------------ (ln 1 = 0)

= 1/3 x -ln2 = -1/3ln2

what's the point of putting it in the second form? would it not be simpler to just leave it as x= 1/3ln(1/2) and sub that into the original equation

yay, finally finished the question. thanks so much to you for all of your help. kinda off the topic but how did you all get so good at maths? you'll probably laugh when you read this considering the number of stupid questions i ask, but im actually the best in my maths class and always get close to full marks in the mocks, but you are all way, way better than me. are you all doing maths degrees or fm, or are you just good at maths?

You really get close to full marks in mocks? Surprising to say the least, but well done!

I've just finished a-level maths and further maths, so extra practice always helps.

yeah, not as dumb as i seem. or maybe i just ask loads of dumb questions so i dont ponder over them in the actual exam. not that impressive considering half our class got an A in C1, but i got 99 so i cant be that bad at maths

C1 really isn't hard though. You just have to be good at not making mistakes to get a good mark. You wait till C3/C4. They seem easy now compared to FP2/FP3 but they're still much harder than C1.

You're not dumb, but I think you need to spend more time on logs, and perhaps try and read up on the theory before you start an exercise in a particular chapter. I found that amazingly helpful when I was doing C2/C3.
