Higher Maths CfE 2015-2016

Finding it really good so far.
Just started differentiation.
Hoping to get A1.
What about you?

Im finding it pretty boring this year, it's quite easy (the first part anyway) I'm doing graphs and functions and just finished straight lines. Im hoping for an A too, band 1/2 doesn't really matter to me. Do you have books/study guides that you'd recommend ?

I have the Heinemann Higher Maths (2nd edition) and I would highly recommend it because it's really good with lots of questions for practice.

I wouldn't get the "how to pass" guides if you are aiming for an A as they are quite basic and only enough to get a C in my opinion.

Same book here

Do you think it's good?

I would say so yes, but it seems like a hell lot of questions and sometimes I have heard apparantley the how to pass is better but yeah it is a good textbook definitely

absolutely terrified about this year exam because sure sqa won't make it as hard but it will be quite hard still otherwise previous year will complain. Probably also the fact that nothing whatsoever makes sense in higher. Nat 5 was a walk in the park compared to this. I go to a private school, have a tutor, got A at Nat 5 maths, doing higher maths questions everyday and still not coming to me

That sucks, I hope it gets better for you. If you need any help, I'd be happy to help you

Thanks Man, I'll post questions on here when I'm stuck from now on. Thanks for the offer

I am doing Advanced Higher Maths this year and I also sat CFE higher maths last year. Just give me a shout if you any help!

Aka quote me.

Do you know when you get a function question and it asks for the value it cant be ? the domain or something? I dont know what to do for it?

You have to be a bit careful with your terminology. The domain is what you input to the function. The range is the output. I'm guessing you're referring to questions which say 'what values of x cannot be included in the domain of this function?'
What that means is what values of x can you NOT put into the function.
I sat old Higher Maths last year and as far as I can remember, there are only two basic rules you have to remember:
1. You cannot divide by zero.
E.g. 2/(x^2 +6x + 9) = 0
You have a fraction so now the denominator can NEVER be 0. You simply factorize the quadratic and you will find x = 3,-3. So x can't be 3 or -3.
In the exam, you would write this as ' x ≠3 & x ≠-3'.
2. You can't calculate the square root of negative.
E.g. √(x^2-9) = 0
Using the second rule, we know that whatever is inside the square root(in this case, x^2-9) cannot be less than 0.
If you were told to find the values of x which cannot be included on the domain, you will make an equation to find what values of x will make the value inside the square root less than zero, x^2-9 <0(the value can be 0 exactly, so that's why I didn't include the less than or equal to sign).
This is an inequality which you will have to solve. You will be taught about these later on in the course so don't worry too much about it now. However you should get the answer -3< x < 3.

Sorry if it this was a bit lengthy, but this is just from my experience from the old Higher. I'm not sure how much different the New Higher is.

Anybody have any idea how I would do part b of this question? Thanks
