Y_Shun SG Hello... Can some maths pro please share your msn here if you don't mind...o.O or PM it to me...keke I have a few questions to ask...(or get hints from you to do it) In my opinion, I feel that posting here quite troublesome sometimes...have to upload etc.
Y_Shun SG Oh yeah...to save time, I think I still upload first. DOC: http://www.twango.com/media/yongshun.public/yongshun.10001 PDF: http://www.twango.com/media/yongshun.public/yongshun.10002 My school prelim AMATH questions, these are the questions I am wrong in, so want to ask here how to solve it.

eagle SG Just a tip for the trigo identity in Prelim 2 Do from RHS. Also, convert all trigo identities to just sin and cos for easier manipulation
^tamago^ SG 4. (1-cos²x)(3-2sin²x)=1 sin²x(3-2sin²x)=1 2(sin²x)²-3sin²x+1=0 (2sin²x-1)(sin²x-1)=0 sin²x = 1 or ½ sin x = ±1, ±sqrt(½) For 0 1. RHS = 1/(sec x-tan x) = (sec²x-tan²x)/(sec x-tan x) sec²x-tan²x=1 = sec x+tan x a²-b²=(a+b)(a-b) = LHS
HyuugaNeji SG Originally posted by ^tamago^: [b]2. this part should be 8/3, not 6. Otherwise, good job.
Y_Shun SG Originally posted by ^tamago^: 2. first of all, TY to those who helped me to solve the qtns! ^.^ next right, i want to ask this qwtn..where did u get the 8/3 thingy?
