ya, but be aware that there was a +/- sign throughout which eventually cancels out.. but i dunno if they'll mark u down if u dont write it.5. a)
iv)
t = pi/3n

Woah everything?i know all the top 5 guys in my school got everything
sooooo happy
What +/- sign?ya, but be aware that there was a +/- sign throughout which eventually cancels out.. but i dunno if they'll mark u down if u dont write it.
yeh but in part 3 it asked for veolocity, but dw i HIHGLY doubt they'll take marks off for itthere wasnt cause it asked for speed = |velocity|
Look at the wording of the question7. b) ii)
did we have to check the nature of the point, becuase seriously
...
i differentiated implicitly and the 2nd derivative/1st derivative (checking each side) was a monster
You had to find the area of the triangle and then just multiply by 10.how did ppl work out the Volume 1... i could not work it out!!!
oh no... dnt tell me it was as simple as [5h^2*root3]/2
plz dnt tell me i just worked it out
EDIT: no thats wrong... phew!
yer i couldnt find the area...You had to find the area of the triangle and then just multiply by 10.
This is what I did: was isoceles. Construct a line through the middle, form 2 equal right angled triangles. We know the height is h, and we know the angles of the triangle. Use trig to find out the length of the base of the triangle. That gives you 2 sides, which you can use to find the area, which you just multiply through by 10.
yepyer i couldnt find the area...
did u keep it as a trig ratio but... coz from wat i remember htere the other sides were unkown
