Would I get 0 or 1 out of 2 marks for:
12. b) ii) Finding p=4 but not finding Q
12. c) ii) Finding OB and using the cosine rule but using angle BOA, hence unable to find h.
14. c) iii) Finding the sum but not multiplying the entire thing 2^(2n+1)
Wrote down the eqn of the Volume of the cylinder and compared it to the one that they gave us. Noticed that their answer didn't have a 'y' but R and H instead, so u had to find an eqn that related y to R and H. Similar triangles took me a minute to figure out maybe cause its similar to rates of...
