collinear vectors are those in a straight line

 

[scarificeurlaav]

collinear vectors are those in a straight line

so they're not parallel right?

 

[kitecrystal]

so they're not parallel right?

Colinear Vectors are also Parallel vectors except that they lie on the same line.

only if you are left with time

TIME?
It is the only thing that never abandons you in Both Math Exams! (For me atleast)
Time is rarely any issue for anyone doing bad!

Dude I am never left with time in P2 .. because of those stupid graphs! they take atleast 15-20 minutes of my time in plotting! I am hoping only one graph comes in section B, with easier alternatives .. so I can leave the graph and do the others.. !!!

Q 12, which test was harder?
I know you wouldn't want to draw the graph for the first test, but here's the complete info: 19 % of the students took atleast 95 mins to complete the first test, and in the second test 25 % of the students took at least 95 mins.
So which one's harder?
