The area of the integration one was something like 499/24, you had to find the small area under the curve from 3.0 to 3.5 by integrating and adding the trapezium.

The differentiation question you had to differentiate the equation, set it to 0 for the maximum, and get the larger value, then you had to substitute it into the d2V/dx2 to get a negative value and prove that it was maximum

By the way the answer for the differentiation one was 3.03, just confirmed it. You hd to reject the 10.3 one.

The log part b was log2/log3 confirmed aswell.

The triangle one was 5sqrt305/2

for volume question, wasnt it like 3.03?

It was really hard

Yes the answer was 499/24, you probably got it right since it was divided by 24. And maybe, didnt seem too hard other than the bearing one.

I had to completely skip the last question and somehow went halfway correct of that volume question then gave up after getting positive value(s)... Anyone remembers the marks of these two questions? Solving papers of last five years. I can honestly say this was far by the hardest C12 paper 😭😭
