Na I got 14, I accidentally wrote 15 because I was thinking of k+1Binomial was k=14 pretty surr
Maybe 50/70, I really don't know. I'm Disappointed.Predictions for E4 cutoff?
I admit this paper was more doable than previous years. However, I definitely didnt perform the best I could today. I'm sad because i prepared hard for 3U for the past 2 years too...
It’s alright man, same thing happened with 4u for me. Completely bombed 13 out, somehow did most of 16 but missed out on early marks. It’ll get better from hereMaybe 50/70, I really don't know. I'm Disappointed.
sqrt6/sqrt2 simplifies to sqrt3 which is an exact value of tanFor the Rcos(x- alpha) did you guys get tan^-1(sqrt6/sqrt2) and did you leave it like that when subbing back inti the Rcos(x-alpha)?
that’s sqrt3 which means alpha is pi/3For the Rcos(x- alpha) did you guys get tan^-1(sqrt6/sqrt2) and did you leave it like that when subbing back inti the Rcos(x-alpha)?
Ohhhh no I forgot tht do you think I lose a mark or two?sqrt6/sqrt2 simplifies to sqrt3 which is an exact value of tan
Unfortunately but did you still plug in the number into your calculator to get pi/3?Ohhhh no I forgot tht do you think I lose a mark or two?
E4 at the minimum, so maybe 90-92What do you guys think 57-60 out of 70 will scale to?
No, I just left it tan^-1(sqrt6/sqrt2) ... do you think loss of 1 or 2 marks?Unfortunately but did you still plug in the number into your calculator to get pi/3?
Only 1 mark, I’d sayNo, I just left it tan^-1(sqrt6/sqrt2) ... do you think loss of 1 or 2 marks?
But the domain for f(x) was x>=1 so wouldn’t the range for f-1(x) have been f(x)>=1?I got 3 solutions for question 10 bcuz the domain was in between -1 and 0 and hence the sole were at x=-1, x=0 and x=somethin like -0.62
but then again, im not a nurd
