I know about it, but i think downloading it is better, because accessing it from the internet will be slower.

Guys,

I'm having trouble with chapter 1 Fp2, and finding the horizontal asymptote.

Can anyone help ?

Have you got a question you're struggling with? The inequalities topic has so many methods, so you may find one that you find easier.

[raheem94]

If we have a question of the type, , we need to differentiate it, the book usually solves these in the following way:


Why can't we do it in the following way?


Comparing, the above formula, this with the question, , we can directly write the answer, Notice the '2' at the top is obtained by differentiating '2x'.

Thanks in advance

If by comparing you mean applying the chain rule, then yes its completely valid.

You can do it that way; that's what I do anyway and it's 100% correct as it's just the chain rule.

I was confused because the book never mentions this method, i just deduced it while doing questions.

From past experience, Edexcel will guide you towards the first method if that's what they want.

For example:

Differentiate by using the result .

Bit of a shameless plug, but there might still be some interesting questions left in the thread I made last year. Oh, and good luck all

Thanks. How did you do in FP2/FP3, if you dont mind me asking?

If I remember correctly, 80 and 96 in 2 and 3 respectively. Made a very stupid mistake on the very last question on the 2011 paper if you were interested .

Nice scores! I'm guessing you got the A*?

Can you give an example question?

I'd have to fish for it. I'd do it after some time. Focused on S2 and D1 for now

Is there no general method for finding a horizontal asymptote ?

Are you having trouble on questions like this:

It is clear that the vertical asymptote will be , but the horizontal asymptote isn't clear.

One way of finding the horizontal asymptote is to rearrange the expression to get , so we can notice that the horizontal asymptote will be

Do you want an easier approach for finding the horizontal asymptote?
