Solomon papers are all of the same difficulty level (at least thats what i think) unlike edexcel where some papers are easy while others are hard. So for solomon papers it doesn't really matter which one you do, seeing you don't have enough time, i would say why don't you do alternative? like do paper A solomon then go to paper C, E etc. Yes definitely need to invest more time on maths. PRACTICE is the key.
Anyway good luck.
Thank you! Hopefully I'll be okay, need an A in maths :/.
heey, for the R-addition formulas, do we have to know how to prove how we get these? Or do we just need to know how to use them to prove identities and find R and alpha etc, if this makes sense?
Just a quick question about functions. Why is f(x) = Square root x, a function if domain is x>=0, since it still remains a mapping of one-to-many (for every +/- y there is an x value).

I'm pretty sure that's wrong. Where did you see this?

Maybe I am sketching the wrong thing..but if am write that's a function and it's not 1 to many nor its' many to one
When proving trig, do you always need to start with the left hand side to prove the right hand side, or can you start from the RHS and work to the LHS? Asking because there are a few which I find easier/quicker to do the other way round.

Start from any side, but advice is to start from the side that is easier to equate to the other. Normally the longer side is easier to convert into the smaller side.

f(x)=x,x≥0
Is not a function, for the reasons you've given. However
f(x)=+x,x≥0
The modified version is usually used to comply with the function definition
yhh +root x is a function with the parametres defined as x> or equal to 0, however ±root x isn't a function because y cannot be uniquely defined in terms of x, since many values of y map to one value of x

can i ask what the answers are to see if i am correct please
There was some trig identity that I just cannot remember! It was something to do with -sina or something I think. Apparently it never comes up but I still want to know it! Please help if anyone knows what on earth I'm on about
hey guys, i was wondering whether anyone could help me solve this trig question: Solve: 3cot2x + cotx = 1
Also, if possible, explain your method, haha thanks!!
convert all cot to 1/tan then basically use double angle identity for tan2x you should get a quadratic then solve the quadratic in this domain -π/2<x<π/2 my ans. are π/4 and -1.03
