Are proofs of a formula really needed to learned? watch

    So I see that sometimes we are taught the proof of a certain formula and why that formula works but would it be likely for an exam question to ask us for the proof of a formula (besides the identities stuff but any other formula)

    For example, proof of Integration by parts in C4 won't stick into my head

    I suppose not, like are we really going to need to learn algebra too?

    It's just to pass the grade really...

    I can't tell if you're being sarcastic with the algebra part and didn't understand my question

    These are the types of proofs I am talking about: http://www.examsolutions.net/maths-r...arts/proof.php

    I understand the formulas and I can apply them but proving the formula myself is what I struggle with

    They don't need to be learnt, they need to be understood. Unless you want to be a mindless exam drone? :dontknow:

    Thanks for the response! So OCR would never ask such proof of formula questions? Great lol

    You could have a look here, from page 34
    http://ocr.org.uk/Images/67746-specification.pdf

    I didn't spot anywhere that it asked for proofs in C1 or C2 for instance, whereas Edexcel do expect you to be able to prove the sum formulae for arithmetic and geometric series.

    Thanks, I am currently reading that.

    Not having a go here but I really don't understand how you (or anyone for that matter) can be doing A2 maths and not care about the proofs/derivation of formula :ashamed:

    Reading them through and thinking about how they work is one thing. Learning them so that you can produce them in an exam is something different.

    If you're planning to do Maths at university, come back and read this thread again in a couple of years' time.

    I don't mean learn them off, but just reading and appreciating them is all

    The original question was about whether an exam question would ask you to prove a formula.

    I want to do well in the exam and if anything that comes up that I struggle with would be a huge downside for me! This thread was just to simply see whether the one thing I struggle with, would or would not come up in the exam. Anyone doing Mathematics at A-level is doing Maths because they're good at it, like it and it is helpful for whatever degree they want to study - not because they care about derivations of formula.
