If paper 1 is examcraft for a subject would that mean paper 2 is definitely examcraft as well.

Very likely, but not guaranteed, schools have been known to mix and match to throw off people who go looking for hints on the internet / from friends in other schools ...

Maths Paper 1 HL Debs: Keep in mind, if you're going to cheat the entire exam... it will not represent your ability, at all. I was really reluctant to post this, but I guess it's not my problem what you do with it.

btw on a note, if anyone does out the solutions for the long questions, and could send some my way.. still at a total loss how to do the Q8, i did pretty well in the

exponential function

one thankfully.

I DON'T HAVE THE SOLUTIONS, PLEASE.. DON'T PM ME!

Qu 1.
The number of users on a social network doubles every week. in week 1, there are 24, week 2, 48 etc.
i. How many users access in week 12.
ii. In which week does the number exceed 10million.
iii. Users visiting the site average 10 times a week, the website earns .4 cent per visit, how much revenue is generated in 12 weeks.
b) the sum to infinity of 5+10x+20x^2+40x^3 is 100
Find x.

Qu2.
f(x)= (x-2)/(x-4)
Show that it has no local min or max points.
Find the equations of the asymptotes and sketch the curve f(x)
Show that no two tangents are perpendicular to eachother.

Qu3.
4 complex numbers shown on argand diagram, same scale is used on both axes, z1 has a modulus less than 1.
Which of these numbers best represents Z1^2
Plot the relative positions of iz1 and z1conjugate, label both.
Let w= (CosPI/18+iSinPI/18)^11/(CosPI/36+iSinPI/36)^4

Express w in the form a+bi

Find the two complex numbers x+yi for witch (x+yi)^2=w

Qu4.
g(x)= sqrt 4x-3 (graphed on diagram)
State if it is injective or not.
Under what criteria is it bijective, codomain and domain.
Find the inverse function and then sketch it.

Qu5.

Shows two graphs, |2x-3| and 3+3x-x^2
Use the graph to solve inequality |2x-3|>3+3x-x^2
Use algebra to solve it.
Find the value of m for which |2x-3|=mx+1

Qu.6
4 graphs, which is is the function x(1-x)^3(3-x)^2

b) g(x)=ax^3+bx^2+cx+d
local max at x=p, min at x=q

Show that p+q=2t

Given that it only has one turning point, express a in terms of b and c.
Hence, find coordinates of the point in terms of b,c,d

Qu7
exponential growth.
dN/DT= kN

Show that N(t)=N0e^kt satisfies Dn/dt=kN where N0 is quantity at t=0
Deduce lnN=kt+c

Suggest a limitation of using exponential functions to model physical phenomenon, and give a reason for it.

b)
Equation: lnA=-kt+lnA0, A0 is initial concentration of a substance, A is concentration at time t
there's a table with time and concentrations, ill edit it tomorrow, far too late right now.

You have to plug the numbers into the equation and get values for A, then graph it.. easy enough.

Using the graph, or otherwise, find the value of k.
The concentration of the substance when complete is .015 moles... using your value of k, find the time it took for the experiment to the nearest minute.

Show that A(T) is always increasing.
Find the half life of the substance.

Qu8.
Diagram hasa right angled, circular based, cone. slant=l, makes an angle theta with the vertical
Express radius and height in terms of l and thetha,
show that V=piL^3/6 (SinTHETAsin2THETHA)

Find value of thetha for which the cone is at max volume. give answer in form tan^-1sqrtA
Find the max volume, in surd form

b) A lot of text, about a water tower. basically it's a cone, inverted, with a vertical angle thetha of 45*, with radius r. DX/DT=root2
X is the fall in slant hiehg, in metres, from the max capacity, at time t, in hours
Find the max capacity of the reservoir.
Hence, show that volume of water in the tank at time t is pi/6root2 (l-x)^3
Find in terms of l and t the rate at which the volume is decreasing.
Find the rate when the capacity is at 1/8 max.
Given that an example of this tower has a slant 30metres, how long would it take to empty the tank.

Qu9.
Mary and john take out mortgage of 400,000
they agree to repay the loan, and interest, in monthly repayments. for 20 years
effective annual rate is 6%

Show that the monthly rate is .487%
Use geometric series to calculate monthly repayments.
Using amortisation, verify answer.

b) After two years, their financial situation suffered.. they cant repay the loan..
Find the amount outstanding on the loan, correct to nearest cent.
ii) The lender charges an additional 1.5% per annum on the loans in arrears, compounded monthly, how long will it take to exceed original sum of money borrowed..
Give one justification why there's an extra interest for loans in arrears.

Paper 2 tomorrow.

Maths Paper 1 Exam craft Honours

1) Know the proof by contradiction. Know what an irrational number is. Know root 2 contradiction proof. Also know what where an irrational number would be placed in the number system.
2) Not too sure but there was definitely 3 simultaneous eqn. More algebra eqns.
3) Algebra questions.
4) Complex numbers. Have to right a rectangular form into polar form. Then use this to apply De Moivres theorem
5) you have three fucntions and you have to say if they are injective, Bijective, Surjective.
There is a log question-not hard
6) Financial maths, the first question might as well have been Chinese but the rest wasnt too bad. Learn how to deal with mortgages.
7) integration, not difficult, know how to integrate an equation and cos and sin
8) I couldnt do this question but it was a prisim that was in the shape of a trough (I dont know how to spell it but its what animals drink from) Know volume and then rate of change
9) This took me ages to count the cubes Properly. It is a quadratic and the common number between them is 6. Then know the nth term. Not hard as long as you count the cubes right.

No point pming me for answers cause I know I did bad!
