    Trapezium rule in C4 usual comes with an integration question, one may be asked to compare the two results, and the functions are more complicated....however, little else, is still the same old trapezium rule

    simpsons rule is not on c4[edexcel] thank god [even though i don't know what it is].

    I just did a stupid solomon question with trapezium rule.

    I used degrees and not radians and got a totall diff answer, the question didnt even say do it in radians. WTF is going on, if it is like this next tuesday im screwed :eek: .

    Are we meant to use radians in the trapezium rule always?

    Yep thats C3 OCR, because theres cw in it simpsons rule is part of the little bit of numerical methods involved in C3.

    Yes you should get used to radians by C4, also the trignometrical functions, and there derivatives require that you use radians.

    i remember reading (in C3) that we can only differentiate when in radians. it would follow to be the same thing for integration

    Yes thats correct, the derivatives of the trig functions only work to give the gradient at a given point of the function if the angle is given in radians, which makes sense really
