I'm currently studying A-Level maths just started and I was wondering anyone who already done it or is still doing has any suggestions for any books which could possibly help me to understand topics better, more in-depth explanation.

In GCSE i studied Intermediate Maths and got a B highest grade and since i didn't study for the Higher paper things that I'm learning now in A-level are new to me well majority.

For the first year, AS I'm doing C1, C2 and D1 so Core Mathematics 1 and 2 and than Decision Making. I know there are probably 100s of books out there to help with a-level maths but i was wondering anyone who has any good suggestions that they might of used some books.

Thanks in advance

How do you isolate for x? Everything I have tried results in one of the x variables being part of a trig function. (I am trying to find the inverse of this function, so if it is not possible to isolate for x, how do you find the inverse?

There is a squirrel. He buries acorns 9 inches apart along a 3-foot long line, then turns 90° and buries acorns in a straight line for another 3 feet, and continues in this manner until he has completed a perfect square. Each side of the square is three feet long. how many acorns Square Sam buries to complete his square? please help asap!!!

If the Quadratic equation αx2 + βx + a2 + b2 + c2 – ab – bc – ca = 0 has imaginary roots, then

1. 2(α – β ) + (a-b)2 + (b-c)2 + (c-a)2 > 0
2. 2(α – β ) + (a-b)2 + (b-c)2 + (c-a)2 < 0
3. 2(α – β ) + (a-b)2 + (b-c)2 + (c-a)2 = 0
4. none of these

My family has some interest in some property. The interest is divided as follows:

1/24 x 7/8 = .03645833 - $1455 appraised value my share
1/24 x 1/8 = .00520330 - $2358 appraised value rest of family's share
$3813 Total appraised value
The ownership is changing as follows:

1/24 x 1/4 = .01041667 for my share
1/24 x 3/4 = .03125000 rest of family's share
I need to reapportion the total appraisal of $3813 among the new figures. Can you give me the correct calculation, not just the answer? I have been pretty sick lately and can't seem to work this out in my head the right way.

what are the 3 co ordinates of f(x)=x(x-4)(x+2)....

i know that the 3 co ordinates of, say, f(x)=(x-2)(x-3)(x-1) are 2, 3, and 1. But I'm not sure when there aren't 3 set brackets like in the question.

Thanks

(a) A circle has radius 2cm (in that circle there is an triangle AOB) and the chord AB has length 3cm. AO is 2cm and BO is 2cm. O is the centre of the circle.

(b) consider a paper disc whose boundary is the circle in part (a). The sector AOB is removed from the paper disc and the remaining paper is bent round to form a shallow cone by joining the edge OB to the edge OA.

(i) Which arc becomes the circle that is at the base of the cone? Find the angle subtended by this arc in the original circle (in radians), and hence find the length of the arc.

(ii) Hence find the radius of the circle that is at the base of the cone.

(iii) Find the perpendicular height of the cone.

(iv)Given that the formula for the volume of a cone is
V = 1/3 pie r^2 h
(Where r is the radius of the base and h is the perpendicular
Height), find the volume of the cone in this question.
