I got MC 10 down to b or c and guessed c (didn't have time to do it properly) and fucks me how to do 6.

general formula for sinx is x=180n+(-1)^n .a (general formula for sinx)
so the formula for sin2x would be 2x= 180n+(-1)^n .a (same thing)
so its x= general formula/2 (which is b))

I got the same.

Got this also.

For 11 d) can anyone tell me what the graph looked like??

I understand that if you break the e4 cut off point your exam mark becomes 90 or higher but what does your exam mark become if you get e3?

 

[bunnypacman]

Also for d)ii- what was the value for t when "P is closest to l"?

t=1

Asymptotes x=2 x=-2 and y=0 (the x axis). As x went to infintity y approached zero from below as x went to negative infinity x approached zero from above and the bit between x=-2 and x=2 looked sort of like y=x^3 but the inflection point was not horizontal.

t=1

Yay!

Wow really...btw big fan realisenothing you smashed 4 unit..i got like >74 raw what do you think that would equate to

74 raw will probably be 93 in 4U. 92 at the lowest.

 

[RealiseNothing]

are you sure? what was cut off 97 last year?

97 last year was like 64 or 65/70

 

[hayabusaboston]

Fucking MC, I fell for the tricks lol christ, 6/10. Otherwise altogether I think I got 62-63/70.

 

[yasminee96]

are you sure? what was cut off 97 last year?

I got 96 in my exam last year and based on the solutions, i estimate my raw to have been 59-62/70

 

[kalstar]

What do you guys think a 50/70 will get me? (Worst case)

 

[hayabusaboston]

Realise, 70/70 u reckon?

 

[bunnypacman]

So I'm guessing 44/70 would be E3?

 

[Hezz96]

Does e3 mean greater than or equal to 80?

Yepp

 

[Mitsunami]

Pretty well done, except for the binomial question. As for the other questions I think it's smooth sailing for me.

What do you reckon a 55/70 would get me?
