a math problem.
bro jus called me at work jus now. surpising eh. not until you hear wat he wanted to ask. A MATH PROBLEM. like, his a-math exam paper's later today? well done there.
anyway this is interesting. so i shall go into the details.
'jie, does sec^2x = 0 have a solution?'
'why would it.'
'er cos it would be 1/(cos^2x) and so i thot that i could introduce cos^3x on both sides, making it cosx = 0..'
'eh. liddat u're introducing new solutions leh. if u can do as such, u mus as well tell me given sinx = 0, i can make it cosxsinx = 0, cos i intro cosx to both sides..'
'oh yar hor. hehe. so ok la. sec^2x = 0 is jus n.a.'
'yar. eh anw hold on. you tell me. will 1/anything ever be zero.'
'eh. no hor.'
'yar! cos even 1/0 is infinity. (which ACTUALLY means 1/infinity = 0, but i bet no one wans to solve cos^2x = infinity) ANYWAY. see ah. wats the identity for sec^2x? tan^2x + 1 right? sub that in n u'll get tan^2x = -1 which onces again is n.a. cos you cant root a negative no.'
'wah yar hor. eh jie. U JUS GAVE ME 3 SOLUTIONS..'
'eh yar hor. it jus came naturally leh. haha. shows tt i think thru my stuff thoroughly. hee.'
man i'm good at this. goes well to show that i think TOO much too tho.
