hey, guys, how did you all do?
Did you find it alright? I thought it was ok. Could anyone remember the answers post their answers here. I will try my best to recall some of those.
If, luckily, Mr M comes here, could you pls post the right answers here? Thank you so much.
The question about binomial expansion, I got 1/3 for a, and 7/3 for b. Question 7, the one about integrate sinx and cosx, i got (pi/2-ln2)
The question about the value of 'P', i think it's question 9, I got -1,-4,5 for the values of p.
Question8, the one about water depth in the tank, i got 8.5 minutes for the value of t when x=0.5.
Somehow, I am not very comfortable with my answers....
