mu=4/15 and lamda was -10/11

how did you express it in terms of meu alone (part 3, i think). i just couldn't figure it out. + i didn't manage my time properly. forgot to take double derivative in f''(x). and i couldn't figure out the co-ordinates of P. all this because of over-confidence.
Ma'sha'Allah you seen really pleased.
P2 however went amazing alhamdulillah.
