C1 & C2 Discussion here!
hdbkiwi:
So now that it's been a day, we can discuss!
How did you find C1 and C2?
I found C1 to be great; C2 I had one question with solving the trigonometric equations... how did you guys find it?
master786:
which part of the trignometric question ...
i made the stupidest mistake :P the question where they asked write down f(k).... i just made k the subject and showed it :p ... we had to put k in as x though..
justloosing tht mark ... otherwise C2 was pretty straight forward...
hdbkiwi:
Ah well you'll only lose a couple marks-still great :)
The question with (1+tanx)(Sinx+...(was it 5?))=1(can't remember this side either lol)
what did you do for that?
master786:
equate each bracket to 0
nd continue with the sum
1+tanx= 0
tan inverseof -1 ... and continue :P
hdbkiwi:
ahh good good.. so solve for sin and tan and then get all the different values between -180 and 180?
