-Cornea:
do i need to know how to prove that sin(A+B)=sinA cosB + cosA sinB =D because i can't get it from the book =(

The Golden Girl =D:
Give me a couple of minutes to type it down ..Okies ;)

[ Will be editing so check after some time ]


My teacher told me that there is no need for me to know How to prove this but if it's the Opposite of what my teacher said then please do tell me how we rpove it (:

I hope I helped :D

-Cornea:
and i need to ask if u know what marks should i get in order to score an A* in my AL's if u have an idea about this ,i'll be grateful =}

Malak:
^It all depends on the grade boundary for that year.
But generally you need to get an A in AS in order to get an A* overall and ,I guess, you need like 90% or above in A2 to get an A*
summary: A in AS and 90% (or above) in A2 = A* overall  ::)

-Cornea:
y = 2 – e?^-x iam really confused in these stuff should i multiply it -1 and then add 2 or should i multiply it by 1 only and add 2 then :s
