yes but whats the difference between a definate integral and the area under a curve? nothing, they are the same thing - the same rules apply if its simpsons rule or whether you use integration. I'm pretty sure anyway, if anyone KNOWS i am happy to be corrected

Think about what you have to do when you have a definate integral where parts of the area are under the x-axis and parts of the area are above the x-axis. yes you use the simspons rule as you have quoted but if you do not take into consideration the fact you have a negative area and a positive...

simpsons rule easy as? - i almost got it wrong because i didn't realise till i had finished the question that you had to do it in two parts. the first function was negative, the second was zero and the third was a positive. so you had to calculate from 0.5 to 1 and then add that to the...

i made Gmm a constant and worked out that if 10000 to 20000 takes -1.0M.j then from 0 to 10000 takes -2.0M.j. Thus total to get from 0 to 20000 = -3.0 M.j It takes -0.25M.j to get from 0 to 80000 so to get from 20000 to 80000 its -0.25 - (-3.0) = 2.75M.j Can anyone verfiy?

Does anyone know how accurate the SAM is for calculating a limited uai. A limited uai is calculated on 5 units only (for students 21+). I'm doing 2u maths, physics and adv english and as there will be one unit of the six that wont be counted (undoubtedly english) i put double entries into the...
