integrating with double angles confuse me. and is it 2u or 3u? i shall have my own way doing those questions...and we don't have school on monday, so my questions remained unanswered for 4 days ):
i wish someone gave me worked solutions. i learn from worked solutions, not just answers.
the house i much quieter without my brother.
someone put iceblocks in the fridge today! and i had my free in the middle of the day and it made my day better (: i managed to find a frozen one at the back of the fridge...
people are so generous (:
if happy stuff appears during the middle of the day, i could pass yr 12 happily...i guess...
and just watched (500) days of summer (an hour ago...)
thought it was good the first time. it's actually pretty crap the 2nd time ): like nothing happens... ):
