    I think it is saying what is the Sin of the function from 0 to Pi of X


    But what is that actually doing and why.


    Thanks

    Completely open to correction on this (10 years since I've studied maths)

    Its the integral of the function sin(X) between the limits of 0 and π is equal to 2.

    In plain language I think it's easier to break it down piece by piece.

    Sin(x) is just a trig function. I've always understood functions to simply be an elegant means to describe behaviour (shape of a plot on a graph).

    In this case the sin function describes an oscillating wave pattern. In order to integrate i.e. find the area beneath the curve, you need to specify the limits or boundaries to integrate. In this case, these limits (0, π).

    So I am doing a mass revision for re-exams coming up. To elaborate on this, would it be good to review the background of calculas on this?


    Cheers
