I did the area of the sector so 210/360*pi*radius which was 8 squared and then used the 1/2 x a x b x sinc formula for the two triangles
What about the last one?
thats correct simvib for the last one i wasn't sure i thought 4 was k so i got k^2 then i multiplied the area from the earlier part by it but im not sure on that part.
Hahaha great! I mean the last question of the whole paper did the length of the line = 18.97 or something? And the line of the perpendicular bisector y=-1/3x+4.33
Hahaha great! I mean the last question of the whole paper did the length of the line = 18.97 or something? And the line of the perpendicular bisector y=-1/3x+4.33
yes i rounded it to 3 s.f so 19 and the perpendicular bisector i did the same thing so i think im right..

for the 2 questions before sine rule was involved yeah? and for the mr chan thingy he travelled 1000ish or near that.

I think my answer involved whole integers...I went back to the question with the graph and plotted the lines on there to see if my answers looked right. Do you guys think the grade thresholds will be quite high as it was easy? How did you find it?

there was a question on pythagoras, then the cos rule and then the sine rule, but i think you could have just done 180- two other angles but it was worth 3 marks ,so i used sine as well The mr Chang about 1100 litres, something strange

cosine rule? i didnt use cosine rule in the exam.. and i dont remember 1100 litres. did you add the insurance to the daily price?

I personally think the grade boundary on paper 4 would be about 100 for an A or something like that mean while paper 2 about 49 or 51 for an A

I think you could have used the sine or cosine, but it was four marks, so i used the cosine adn to the mr chang thing it was one thousand something, I just don't remember what, but yes i did add all of it.
