P2 (edexcel) trapezium rule?Watch
does that mean i use values 0.5, 1, 1.5 and 2 or does it mean: 0, 0.5, 1, 1.5 and 2.
Any1 explain the trapezium rule (plz not that long formula its confusin!!) any good sites would b great help cheers!
I would assume you go from zero because otherwise you are missing out part of the area.
As for the trapezium rule, with those values it would be:
Area = 0.5/2(0 + 2(0.5 + 1 + 1.5) + 2)
Hope that helps
