OK. We can try this in ‘08. A section here for Spec students to post questions…
Mr K

For friday…
Are we allowed log book? log books? (then i can use both this yrs and last years log book)
are we allowed calculator? Graphics calculator?
and how do i do this…? I feel dumb…
Chapter Review 1
Q8
if a = 2i-3j+k
if b = -2i+3j+k
What is the unit vector that is both perpendicular to a and b
the answer is 1/root(13) x (3i+2j) or the anti-parallel of that unit vector
I just have no idea what to do… tried dot product, wierdo vector algebera…
THANKS
How to work this out?
Hi
I decided to start holiday work with spesh i finally got stuck
Q7 from page 66, chapter 2.7
“Given that cis 3θ = (cos3θ – 3 cos θ sin2θ) + i (3 cos2θ sin θ – sin3θ), it follows that cos3θ is equal to:”
the answer is D, which is… 4 cos3θ – 3 cos θ
how is that the answer? HOW IS THiS demoivre’s theorem? what is this?
enjoy the rest of the short holidays! dipole
Testing 1,2,3
I have no idea what i’m doing
anyway, I finally have a problem with spesh!

New Authors
Hi Spec class…
Yes, I’ve changed the look – what do you think? Also, if you give me your email addresses (in class not on the site!!) I will add you as authors to the site so you can write your own posts. In wordpress you can then use superscripts 2 and other special characters to enhance the maths!!
Kevin, you have already been added, just answer the email that should have come your way, and then start posting.
(a(x - 3))2 = cos(πθ) – c , etc

Solutions to FM Exam 1 on their own page
Just follow the link here or on the right and see if you agree with me. It was all done fairly quickly, but I am confident that they are correct.

Mr K
Year 12 Exam
Hi guys
What did you think of the exam?? I have completed it all and thought it was quite fair. There were a couple of little tricks in there (like some partial fractions antidiff) but on the whole I quite liked it.
Let me know what you thought.
