1. does anyone have a solution to qu 1 on the c3 june 2014 paper..
can't seem to get my head around it at the minute!!
2. The Simpson's Rule Question? This was actually a fairly straight forward Simpson's Rule question as you didn't need to calculate h as it's already given to you (3 metres).

Yo (first value) is 30m and Yn (last value) is also 30m
Y1 is 28, Y3 is 19, Y5 is 18.5, Y7 is 21 - these are your "odd y values"
Y2 is 22, Y4 is 16, Y6 is 20.8 - these are your "even y values"

The Simpson's Rule equation is given to you in the exams, and is h/3[(Yo+Yn)+4(Y1+Y3+Y5+Y7)+2(Y2+Y4+Y 6)]. I always remember it as h/3[(first+last)+4(sum of "odd y values" )+2(sum of "even y values" )]

Hopefully this helps! I'm rubbish at explaining Maths. Dreading tomorrow's exam.

Really? I think the only mistake I made was mistaking a century to be 10 years , but I've known the C3 content for almost a year!

Where did you find hardest?
