So in some questions they want you to get the are under the curve. And because we still live in the dark ages, we're supposed to do that by counting squares, and definitely NOT by the trapezium rule we learned in A level maths, because GOD FORBID we integrate (pun unintended) that into the Physics A level, it's waaaayyy too hard for physics examiners to understand. I'm sorry for that mini-rant, a level physics made me hate physics, which used to be my favorite subject.
Now on with the question lol,
like how would you even count those?? There isn't enough time in the world? Also what the hell is the mark scheme (attached) talking about?
