Hi sir, for 3ii, I equted the coeffeicent to k the constant and not the constant term, how many marks would i get if any? My solutions were 0 and 1/9 by the way. Also for 9ii I got root 3/2 for k which is correct but got a is equal to 10/3? Finally for 9iii i said that the period of tan was pi/a and also wrote "pi/a -x1=x2" and said xq and xw were the solutions. After that o did tan -1 root3 and got pi/3 and 4pi/3 but did not relate them to ax at all, how many dropped?
3ii) I'm not sure what you mean but it sounds wrong.
For the original log question i) I got it down to log3(x^2) -log3(x+4) but I stupidly simplified to log3(x/x+4) so obviously I carried that through to part ii which then gave me a wrong answer.. How many marks would likely I get out of 6?
For question 7iv, how many marks would I lose for doing (153/5) + (53/5) instead of (153/5) + (53/15) ? And for question 9iii how many marks would I lose for pia/3 and 4pia/3 instead of pi/3a and 4pi/3a?
9ii) I made that mistake first time! You might get 1 mark.
7iv) Drop 1 or 2.
I don't guess boundaries.
Thanks for the reply just a few more questions?
Hi 2ii) I got 21. Something I laid it out correctly ie 2r + r3/5 pi then = but then divided by 3/5pi and got wrong answer? ??9iii) I got tan ax then substituted my a value from previous question which i didn't read the question?

how many marks will you lose for the whole of question 1 if I wrote 20= 0.5 x 8 x Y x sin30 but rearranged it wrongly after that and got 5. Then I used cosine to work out part two but used 5 instead of 10.
Thinking that it might be like 63 for 100UMS? 50 for an A?
A bit extremely generous
100 UMS would never be that low, and the paper definitely wasnt that difficult. That said I'm not sure what the grade boundaries will be, but i don't particularly know how everyone else did, probably not as badly as that though, sorry.

I reckon i got 62 so id be very pleased with that but i think its too low especially after looking through the boundaries for the previous years. Itll most likely be 57/58 for an A.

For 9iii I misread the q and used my value for a from the previous question but got the right solutions just with my a subbed in. How many do you think that would lose?
