I'll have a look at that tomorrow, calling it a day now! Tomorrows plan is to do some other subject for the morning and end the day with C3. Is it worth doing tons of questions on 'numerical methods'? - I mean, there's only two things to it and they never change. Only iteration & sign change.
There is a lot of questions in the C3/C4 book but Idk, what dya think I should do?
Just finished going over Trigonometry in the book, dont' the first two pages of the misc questions. The last three questions -Too much effort Decided to just move on
Having trouble with the equation shown, I know how to get the values of x but the problem is what way does the > sign go?
I sort of understand which way it is when working the equation out algebraically. I want to be able to know which way the sign is supposed to go directly from the graph of the function. Is it even possible? I can draw it on my calculator with no problem, but when writing the solution of x, how am I supposed to know which way the > sign is supposed to be? x+2>2x+1
Thanks a lot for your help... but i'm still a little confused on how you got your answer, i'm getting almost the same answer as you but it's with a 1/2e^3 ln(e^2^x+3)+c instead of 1/2 ln(e^2^x+3)+c. Could you go through all the steps of your working please thank you!

is my answer correct? I might be wrong too!
Right the way I did It:
-I looked at the equation. I differentiated the bottom to see if the differential is the same as the top. It's not. - So I worked out what I needed to add to the top to make it equal to the differential of the bottom. -I put a 2 at the top. HOWEVER you cant just put a number there...So to cancel that 2 out, I put 1/2 on the outside. This means, the equation is sill the same.

then just put it in the form of ln(...)
that's it !
Yh you're right thank you so much! You're a great help! Good luck with all your future endeavors!
Bricking it for this exam, managed to just scrape a B overall for AS maths inc a U in stats really need a B overall!!! what are the grade boundaries like for a B? And I havent even started past papers yet... Gotta learn it all first
