Maths P32 GT and paper discussion

[Tulaib]

don't really remember. but sth like -4 ad 3?

-4 and 3 are correct

 

[A star]

-4 and 3 are correct

how did you find it. how did you form the two equations?

mayb a=-3 and b=4

 

[A star]

mayb a=-3 and b=4

how?

 

[panoramafolks]

-4 and 3 are correct

a--3 and b=4 I think

 

[panoramafolks]

how?

sub x=2 in the equation and equate to zero form an equation
sub x=2 in derivative of equation and form another
solve using substitution method

yes but what did you put instead of g(x) yeh i did the same but ran out of time :. couldnt complete the equations :/

ooh i get it now thanks. it was freakin wasy.. i was just harrased :/
and what about that complex no did you get itan(theta)

it was harder than june 13 but not harder than nov 13 , i guess the GT will be 55 , but i want to know how much i can lose in full alevel for the a star if i am a linear ?

 

[A star]

um guys if i can secure in the range 56-59. can i score a 83+ A ? any one? . acording to the Gt of june 2013 it was 53 for an A. any one?

Gt will be lower than 55 bcz even in june 2013 , it was 53.

there isn't a specific threshold for A* , its the same as for an A.

 

[A star]

mo i mean an A that worth around 83 percent cause just scraping wouldnt do for me

what was answer of the differential equation question?? was value of C equal to 50ln[1/4]

 

[SalmanPakRocks]

Yup, that was the value of c

 

[Yousef123]

Yup, that was the value of c

i guess it was -ln 2

 

[A*(a*)]

Can someone tell me the time required for population(N) to double?

 

[A star]

i guess it was -ln 2

mine came ln(verysmaaalllco)

 

[A*(a*)]

dN/dt = 0.02N(1-0.01N). N was 20 when t was 0.
Can someone solve the differential equation PLEASEE?
