Can someone explain why this is so significant
Basically for the C part it’s saying it’s significant because the signed area from -2 to 5.442 is the same as the area of r2 which is 20/3. It’s annoying me because I kind of think it’s a dumb question and I can’t wrap my head around why it’s so important. Also this is a level maths and I have never seen them ask a question like this before.
