# C3/C4, which module do these topics fall under Watch

1. Basically the situation is the school are teaching both together, and textbooks have not be given but I know we covered these, but I would like to find some practice questions but also for my own curiosity would like to know which module these are for Edexcel?

The exponential function.
The natural logarithmic function.
Differentiation: The chain rule, implicit differentiation, differentiating the exponential function, natural logarithm, sine and cosine, secant and cosecant functions.
Compound angle formulae: what they are, their use to find trig ratios and to simplify expressions. Proving identities.
Parametric equations: finding derivatives and hence stationary points, tangents, etc. Functions: simple properties, range and domain.
Vectors in 2D: magnitude, scalar product, angles, equations of straight lines.

Also, which one is the hardest in your opinion, as the teacher said they will be using all the hard questions

(Historically my vectors have not been good despite doing M1 and M2, but I get them right in those units)
2. Depends on which exam board you are on. For example some of the topics on C3 for Aqa are on C4 for Edexcel and vice versa.

...
Exponential function, natural log function and all the differentiation EXCEPT implicit should be in C3. Everything else is C4. I think compound formulae might be C3 as well but I forgot.
4. RDK Games is right!!

Look up solution bank on physicsandmathstutor or something, you'll have loads of questions there.

It is fairly easy to answer your question but if you're ever stuck and never get an answer, the spec will tell you.

Your first 4 topics are all C3 and the last 2 are C4.

Personally I struggle with vectors when it comes to non-standard questions (so not like asking for equations or magnitude but stuff like June 2014 last part of the vector question..not much point looking that up until you've done more practice but anyway.

But out of those the first 5 topics are easy after enough practice (in my experience) and the last one can be icky.
6. Vectors are normally in 3D rather than 2D in core 4.

Key:
Core 3
Core 4

They're more fun in FP4 but it's a shame OP will miss out on it

Yeah I found FP4 an enjoyable module.
11. I know that we will be moving onto 3D, but need to learn the principles in 2D so that they're sure we know before we move on with the rest of the course, so doing a bit of revision and also writing some notes for later this year, and hence why I asked originally
