Does the question specifically state that you must use the Simpsons rule?
Does it say 2 applications of the simpsons rule.sPideS said:yes...
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 secondmichael1990 said: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 use those last 3 numbers. (10,19,40) cause you will be adding areas that are already found together.NEVAGIVEUP said: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
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 threemichael1990 said:You can use those last 3 numbers.

e.g. a shape that has vales respectively 12,14,16,17,18
you would use 12,14,16 followed by 16,17,18
It doesn't matter what it looks like though.cxlxoxk said:what everyone is saying is that the question should look like this:
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 valuesmichael1990 said:It doesn't matter what it looks like though.
What happens if they only gave you the measurements? Then what would you do?
ITS NOT MISSING ANY NUMBERS! (not shouting at you, just yeah)NEVAGIVEUP said: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
Sorry to put you through the trouble; but look hereView attachment 17401michael1990 said:Finally found an example.
And worked solution.
LOL.NEVAGIVEUP said:Sorry to put you through the trouble; but look hereView attachment 17401
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 :Smichael1990 said: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?
