For the last part here. I attached a neat version of my method, where I just called the result from c, f.

The markscheme doesn’t want us to do this (note that the paper is not an official paper of any exam board).

The markscheme did the third image below. I am curious how, upon looking at this question, I can know that my method is not required?

Is my method EVER required? Is it allowed?

For this question in particular I got a really nasty sum so I guess in hindsight its too hard for 3 marks?

#

So the way Im thinking ab it now is

#

correct me if Im wrong:

#

**__JS READ THIS
My method is exactly what hte solution (pretty blue writing did)

esxscept they used exponential rules to get rid of the problem of having to deal with the '1' in the f(x), right?

Therefore my method of <attached image> is correct, just, here, it isnt enough to get to something workable?__**

fallow briar its correct but doesnt work nicely yes

therefore, am I correct in saying that, for all A Level FM qus, I can solve by:

subbing in
getting rid of constant term by applying rules of e.g. logarithms or exponents?

#

yep

#

any method is fine as long as it doesnt say dont do it

knotty sparrow May 23, 2025, 3:42 PM

#

fallow briar yep

yeah, make sense

no other tricks for me to learn?

#

n.b. my next use of it is in fp1

fp1 has taylor

i dont think that adds any more methods

#

its js

#

not f(0)...

#

otherwise same?

fallow briar May 23, 2025, 3:43 PM

#

yh same thing

#

i cant think of any tricks
