Hi Mr M. Thanks for the answers a usual,
1. For 6ii) i showed how the inequality was formed, however did not read the question and did not find N, how many marks lost.
2. For 7ii) I differentiated the curve, found the tangent equation and that it crosses the x axis as 5/3, however after this i integrated between 5/3 and 1 which i have now realized was wrong, how many marks lost?
Thanks, Z
