Is this question supposed to read: 5562 – 1362 – 1362 + 4162 ???

It's about time the unis woke up and got out of the 1970s. General Maths is actually quite good preparation for any student doing subjects like psychology and offered limited preparation for stats subjects. 2u and 3u maths obviously has no stats but loads of calculus so those subjects are for...

Maths lectures.

I actually prefer a different method. Treat the question in "cases". Case 1: The denominator is positive. So if x – 2 > 0, we have x > 2 And therefore: 1 / (x – 2) < 1 Multiply by the denominator (which is positive): 1 < x – 2 Add 2 to both sides 3 < x x > 3 Since x > 2 and x > 3, we can see...

* The Armstrong & Miller Show - surprisingly good stuff, hopefully ABC will show the 2nd series next year * Black Adder - classic stuff * Allo Allo - saw it again on TV recently, still as good as it was 20 years ago * Mr Bean - of course * Big Train - very under-rated sketch show from the late...

Best GAME of ALL TIME? This question could possibly do with some parameters. Surely the game of Chess would be up at the top? Video game? I'd back Tetris or Pac-Man.

Remember that the area of an ellipse is πab, where a and b are the "radii". So Area of smaller ellipse = πab = π x 8 x 2.5 = 62.8 cm2

I remember that Excel has a cute little pocket book which summarises the whole General Course. I've seen a couple of them, but I've not seen them in shops. Something else you might like is a set of study cards which are available from Jacaranda Press. You can buy them in shops, or you can even...

That hockey/tennis question ... 18% play tennis AND hockey 65% play tennis 65 - 18 = 47, so 47% play tennis ONLY Now we have 15% playing no sport 18% playing both sports 47% playing tennis This adds up to 80% 100 - 80 = 20, so 20% play hockey ONLY. 20% play hockey only 18% play hockey AND...

"Show" just means that you should set out your working as you normally would, working towards the answer. Pretend that you don't know the answer. The perimeter of the rectangle must be 16 metres. Let x be the length and y be the width. P = 2(x + y) = 16 2x + 2y = 16 2y = 16 – 2x y = 8 – x So...

Yeah. The unis are still doing things the same way they did it in the 80s when students had an aggregate mark out of 500 (i.e. best 10 units). General Maths is probably MORE useful for many degrees because of the head start it gives students in statistics. Good for psychology and stuff like that.

If the line looks like / then it will have a positive gradient. If the line looks like \ then it will have a negative gradient. The best way to do this is always work left to right. The run is how far you go across. Because you're going left to right, the run is always positive. Then work out...

n(odd) = 50 n(<30) = 29 n(odd AND <30) = 15 .: P(odd OR <30) = P(odd) + P(<30) – P(odd AND <30) = (50 + 29 – 15)/100 = 64/100 = 16/25

What's your question? Remember that you need to keep the co-ordinates in order. For example, if the first median point is (25,45) and the third median point is (52,18) then: Gradient = Rise/Run = (y2 – y1)/(x2 – x1) = (18 – 25)/(52 – 25) = –27/27 = –1

Maybe he was thinking of this ...

If you're doing a median line of regression then remember you have to split the points into three sections. You then have to find a median point for each of the three sections. Then you draw a line through the first and third median points. Finally, move this line vertically one-third of the...

Actually, after days of looking at that question, it was when I was looking at your first solution that the cosine thing clicked with me. More of a "why didn't I see that before" headache really.

Whoever wrote the question is twisted and evil. Remember that the cosine rule states that a2 = b2 + c2 – 2bc cos A. So each of the three things under the square root signs can be manipulated using the cosine rule. Also remember that cos 45° = 1/√2 but 1/√2 is equal to √2/2, so the √2 in the...

> Do lots and lots of practice questions. Past papers from other schools are probably best at this stage. > If you're OK with the easier questions and worried about harder questions, focus on doing plenty of harder questions.
