Math test...

20/20
i am doing a maths degree though!!
…and in the literacy one i got 11/20 :ermm:

Is it American??? never done a math test in my life. Maths tests on the other hand.

17/20 Not bad considering the only time in my life that I have needed to calculate how long it takes to fill a sink was at school.

I always thought half of what we were taught in maths would have no practical use in later life. I can honestly say that knowing how to deduce the factors of an equation has never been called upon since. IMO maths should be taught as a theory i.e. the big ideas first and then fill in the details. Explain Pi, for instance.

the film? :smiley:

Pi is the ratio between the circumference and the diameter of a circle

Or a lovely treat after tea

17/20 with a fair bit of help from Mrs. Stevie Ramone :smiley:

The book would take some explaining

Sorry too simplistic :). Why is it that particular very very long number?:slight_smile:

Or putting it another way, the area of a circle is a ‘space’ in reality. If you cut out a circle of radius r from a piece of paper it is manifestly ‘there’ and it has a defined and ultimately precise limit. And yet Pi is (apparently?) an infinite number so in calculating the area of the circle using Pi r2 you have contradicted the physical proof before you that the circle is a real defined area…it becomes an infinitely undefinable area…but it isn’t, right??:slight_smile:

I got 20 … I really liked algebra at school and wasn’t bad at it … but in the last year I was moved from the middle set to the top set … so I went from a big fish in a small pond to a small fish in a big pond … didn’t have a clue what was going on … so sat in the corner and didn’t pay attention … shame really …

Did anyone else learn the “cheeky charlie” method for expanding equations? Will stick with me forever :smiley:

I googled and cheeky charlie doesn’t throw anything up … so I’m guessing that my teacher had some unique teaching methods! Anyway - should anyone be interested - cheeky charlie works when you want to expand brackets by drawing lines to make a clown face :smiley:

So (x + 3) (y - 4) expands to 3y + xy - 4x - 12

Clever huh :stuck_out_tongue:

“At least one question (isoceles triangles) is flawed. Equal angles will give equal sides, so either answer is correct but only one is accepted.”

nope, isosceles mean ‘equal legs’ i.e only two sides are equal (=> two angles are equal) what you are referring to is the equilateral

Correct in geometric nomenclature, but that’s not the question.

Pi is just a concept with no actual absolute proof. Other races have got by quite well in maths algebra and a few other things without using 3.1417…etc.

I think I read a year or two back that it had now been proved to be a finite number. Not that it makes much difference if you don’t have a few Cray supercomputers linked up for the weekend.

Now explain “perspective” and the triple vanishing points. Again it just works for us right now.

Pi is slightly wierd. If I say to you ‘go and draw a circle with an area of exactly 1 square metre’ you couldn’t do it. But then I suppose there is no such thing (in a curved universe) as a straight line so it’s equally impossible to draw a square of exactly 1 square metre. Yet we know that 1 square metre must exist because it’s slightly more than 0.999 of a metre and slightly less than 1.001! This is a conundrum I was hoping a degree level mathematician would help me out with.:slight_smile:
