Simpsons rule question (1 Viewer)

Does the question specifically state that you must use the Simpsons rule?

 

[sPideS]

yes...

 

[michael1990]

yes...

Does it say 2 applications of the simpsons rule.
The working out first stated is correct.
You do use 0 as there is no other measurement given. 0 means nothing.

You can't use zero because the four sides of the shape have values, therefore the values must be used, but considering that there are four sides it can't work; unless you use 8, 10, 19 in the 1st application and 10, 19, 40 in the second

You can use those last 3 numbers. (10,19,40) cause you will be adding areas that are already found together.

Then why would we use zero; if zero was to be used then, the diagram should have depicted another line with the value of zero; And when we apply simpsons rule twice that's what we do; we take the 1st and 2nd three
e.g. a shape that has vales respectively 12,14,16,17,18
you would use 12,14,16 followed by 16,17,18

Finally found an example.
And worked solution.

It doesn't matter what it looks like though.

What happens if they only gave you the measurements? Then what would you do?

My point is that they would not give a diagram without the zero, if it needs a zero. There will never be a diagram with a missing value or four values

ITS NOT MISSING ANY NUMBERS! (not shouting at you, just yeah)

You don't need to have 0 written on the diagram. Its logical.

You need two applications of the simpsons rule, if you look at the example i found it does not have 0 on the diagram but 0 is still use in the calculation.
So explain that one if it needs to have the values written?

 

[cxlxoxk]

draw it myself?

lol.


i mean theres always gonna be something that remains constant, and then 3 or 5 other values.

Sorry to put you through the trouble; but look hereView attachment 17401

LOL.

It doesn't matter.
If you were given this question in the hsc, you would just leave it blank? Or use a 0?

Oh well it doesn't matter, we all stated it need 2 applications of the simpsons rule for approximation.

But i do wonder, is that the way the picture was drawn in the question paper?

 

[cxlxoxk]

Just a thought. Would it or would it not be given marks (from positive marking), if we were given a question with 4 values like this one, of decreasing length, to assume in that case, that since the slope is sloping down, that it might not be an asymptotic to a zero level to the left. that it might reach zero at another distance of 12 to the left? and solve it as a 2 applications question.

If it was the question such as your example; i would zero because you can assume it's zero as it depicts it. But if it were the other diagram, then i would not use zero because can't assume zero or bring in another value cos they precisely have given us four, therefore i would use the four, somehow :S

 

[o7nesss]

im pretty sure its mainly on the slopped ends, if theres no measurement, its 0.
thats it!

 

[bomber650]

my maths teacher said if theres 4 measurements (which happens never) use this formula...h/3(df+4dm+4dm+dl).

 

[bomber650]

sorry...fuck up in that...h/4(df+4dm+4dm+dl)
