# Are there any bits of FP1 that will help with Core 1? watch

1. So i've basically finished revising core 1 and am just doing past papers now, but I was wondering if there are any topics in FP1 that will be beneficial for me to self-teach and will come in handy for trickier Core 1 questions?
The only reason i'm asking is because I heard someone saying that they got stuck on a Core 1 question and had to use their 'FP1 techniques'.
2. I think some of the coordinate system questions in FP1 can help quite a bit, and the understanding in some of the series questions for sure. That's in my opinion, though

For differentiation, the chain rule, product rule, and quotient rule from C3 can simplify some questions.
E.g. differentiating (x^2+3)^4, you could multiply it out and then differentiate each term, or just use the chain rule which is much quicker.

As previously mentioned, summation formulae from FP1 can occasionally be useful in sequences/series questions.
For factorising polynomials, the Factor and Remainder Theorems from C2 can be quite helpful.
For coordinate geometry, the "shoelace" formula for finding the area of a triangle given its coordinates can be useful, but it's not essential. (It's not included in any A-Level unit).

Hopefully this helps.
4. I'd say it's not worth the hassle unless you are genuinely interested in the FP1 stuff (which isn't very interesting).
