Um.. i did that.. made all optional.. but with a Condition Exp (or is it Conditional Exp?).. and I didn't loop the end back to the beginning of the part after the REPEAT.. because it is a statement..
Um.. i found it not that hard.. because there weren't any LONG, big mark algorithm questions..
though the part which i probably did worst in was the final part of Evolution of Programming Languages.. didn't know about instances.. LOL!!
well you're supposed to get.. dI/ds (because it asks for lux/m)
and dI/ds = -kI
= -1/6ln6*1000 = -298.6 (as many ppl have said..)
So.. then i guess you put it is decreasing at 298.6 lux/m
Some corrections.. quite sure..
3. b) ii) 1/2ln(2)
4. c) iv) 32/3
NOT SURE: For 7. c) ii) i got 7/27
And overall... I think I have lost 3 marks!! from Silly mistakes! GAH!!
LOL, well you're not even taught to integrate logs in 3u.. i don't think..
anyway, for that one the area was the rectangle minus the area from the curve to the y-axis..
Which you have to change the subject of the curve to x.
Then find the area from there...
I think for the response.. u just gotta show how composers use image to portray chars, settings and themes in texts.. with liek examples from the film and explanations.. like what you would usually do in essays...
and.. camera, colour, settings, costumes.. are all techniques.. and u can talk...
