4. Good luck ya'll!
Any last minute tips for forming differential equations?
5. (Original post by CD223)
Yes that's correct. But if they're perpendicular the direction of the vectors doesn't matter

Oh ok thanks! For differentiak equatiobs could they ask us to form one which is inversely proportional? :/

Possibly'

7. What equations do we need to know? Is it just double angle identities and the ones from core 3?

And triple angle?

And triple angle?
What triple angle? What are they?

Do we need to memorise the equation for sin3x, cos3x, and tan3x?
Whaaaat? What are the equations for these? someone write them here please?

Triple angles:
Sin3x = 3sinx - 4sin³x
Cos3x = 4cos³x - 3cosx
Tan3x = 3tanx - tan³x / 1 - 3tan²x
12. Just use 2x and x for triple angle thdn use double angle for the 2x

13. HYPE!
14. How was it?

It went alright. didn't like question 7
16. what was the coordinates of C?
17. Omg I made a stupid mistake, the question where you had to show that h(x) was decreasing, I accidentally did some weird stuff by finding the second derivative how many marks would I have lost? I did find an equation for the first derivative though
18. I got -9 -2 18, pretty sure I'm wrong tho because I screwed up d
19. How was it?
