Solutions of Y cOs [G ''(x)] = Arcsin [ f '(x) ]

Yesterday was cool.. it started with me deciding to go to school to study some physics early in the morning. But i ended up reading at about 1030... so, i tried to do some problems, but ended up deriving the MIs (ref to previous post). Yup.. then, i went for lunch, and got back to the library.. And met up with qiuhan and her frends @ biz. And studied physics till about 830pm... and then , as i was walking to the biz busstop, i saw my C-Language lecturer filing up his water bottle! Initially, i wanted to say hi to him, but he was facing the cooler.. so i just walked past. And then, somehow, after walking for some distance, i turned around and went back and greeted him. and guess what: I got a lift till Buona Vista! :) haha.. so cool! Ya.. then i took 105 from there... i didn't really take note of the time taken, but just felt that it was much faster..but ya.. it tends to get a bit crowded at the orchard area. No wornder there's always no seats when i try to transfer to it from 151(that's why i prefer transferring to 156 instead:) )
