For the area of the triangle question, couldn't you have integrated the formula of the tangent using 25/8 and 0 as the boundaries? I got the same answer (39.0625) but people are saying that you couldn't do that

in some past papers they have shown that method, you should be fine

For the trapezium integration question, I stupidly integrated the value before the brackets and carried on from there, how many marks will I lose accounting for method marks
Also. My integrated area was massive. 144cm^2. I redid the integration 100 times but I don't see my mistake. Posted from TSR Mobile
Sup, did exactly the same, you and I both integrated the value before the brackets right? You're not meant to do that, if you carried on and multiplied it by 50 then we'll probably get W for method marks
It asked for reported cases or viruses detected iirc, so you had to go with the lowest integer the decimal could provide. I'm not 100% sure on this though.

I got the same thing using area of a triangle formula 1/2*b*h
so 1/2*25*25/8
Your method would take longer and isnt as efficient but is perfectly valid
