oh shitt. I forget to put 1.003 after the 500 in the superannuation question Q_Q. i got 333 too for bearing though. Damn that was a super hard test T.T

 

[PotatoAlpha]

Shouldn't it be 1.003^60 outside the bracket?

Yeah probably, cant even write brackets/fractions using this format

Evaluate the AP 2+5+8+11+....+1094

Just wanna confirm what u guys got for this question ???

@lekawaiicupcake
will you lose a mark if you just cbf'd simplifying the y answer? xD i ran out of space and i didnt wanna ask for another booklet (my excuse for i couldnt be bothered >.>)

Nah I think you should be fine. It would be pretty stupid to allocate a mark for simplification in that Q. Some people even left it as a decimal.

how did you get the coordinates of P

I think I got like 200020

 

[britaker]

so fking easy band 1 here i come

Bahahaha I know right. I know I definitely lost 2 marks but knowing my silly mistake ratio I probably got like 10% lolz.

 

[shved]

how did you get the coordinates of P

use the derivative and simultaneous with mx=e^2x

 

[trungduong12]

How can bearing be 333?
I got 322 :/
Did the cosine rule !!!

there were 365 terms so sum= 365/2(2+1094)

Ok
Got it right

It was like 332 degrees and 31 minutes or something and you round it up

You need to add 11 to that.
I don't remember the exact figures but after subtracting angle bca from 360 you will get 322. But bca includes 11 which should be added back.
If that makes any sense

lol
since the derivative=m and e^2x=mx
just sub out e^2x
divide through by m
and u get x=1/2
