You may assume that 124.6 x 1357 =169082.2 without checking
Using the above result evaluate 123.6 x 1357 by a subtraction method only
By a similar method to that used in 1) calculate 224.6 x 1357 (no credit will be given for direct multiplication)
Write down the value of 169082.2 ÷ 1246
Every generation has geniues and idiots, and it’s hard to compare.
No, it’s easy to compare: a first-year statistics course’ll provide you with the tools to identify trends. See your local university for a statistics class near you! If you think that you can’t analyze data because it can’t always be linearly ordered, then your university education has been for naught.
Easter[n] education is probably the strictest and the most rigorious in the world, but they produce far less Nobelist than North America, and there is a reason for that. This is where a rigorous education is simply not enough.
In any first-year statistics course - you know, the one whose content you obviously don’t get at all - one learns that one can’t compare data sets by looking at the outliers.
Go learn about what that means - independently, in a library - and then we’ll talk.
It occurs to me that comparing the syllabus that English pupils had to master by age 16 in 1982 (those who know me and my age will note that I had mastered it at a somewhat younger age) and the one that North American university students apparently have to master some 2 decades later makes it clear that there is some serious slippage in standards.State the divergence theorem, and give an elementary proof of it. Verify the theorem for the case of the vector field v=(2x, -y2,2x2), taken over the region bounded by x2+y2=4, z=1 and z=3
I doubt I could answer the question now but looking at the exam paper I clearly answered it then and probably did so successfully - although I avoided the question which began with "Starting from Maxwell's equations, show that..." and contained "[You may assume without proof the general solution for Poisson's equation...]".
