today, my sister woke me up by throwing a stack of books on my bed. assessment books and a few textbooks. well, save some money!
there was a A Math exam paper and i looked through it, i got the shock of my life! it was so hard to do, i basically didnt even understand a single question. maybe i'm gonna fail math next year.
eg . The diagram shows a river, 90m wide, flowing at 2ms-1 between parallel banks. A ferry travells in a straight line from a point A to a point B directly opposite A. Given that the ferry takes exactly one minute to cross the river, find
(a) the speed of the ferry in still water, [3]
(b) the angle to the bank which the ferry must be steered [2]
do you have any idea?!
eg.2 Prove the identity : cos x cot x + sin x = cosec x (x = algebra x)
KILL ME!
