1. ### What are the next two numbers in this sequence?

If it's so clear, could you point me to a source that provides an answer? Because I couldn't find one. Also yep, interview application.
2. ### What are the next two numbers in this sequence?

Hey everyone, I came across this question while applying for something. Was totally stumped on it, wondering if anyone has a solution! edit: the question is: What follows in the sequence? 2, 88, 80, 16, 11, 3, 30, 95, ?, ?

hey it's me
4. ### General Thoughts: Mathematics Extension 2

For the last integration question, I left my answer as e^lnx / 1+lnx +c. Will I be marked down for this? Quite disheartening if I do =(
5. ### Module C: Caesar Discussion

I argued it saying that conflicting perspectives are first established through the use of power --> then it is shifted towards the other perspective through the manipulation of form and language techniques to develop the 'truth' of the situation. thoughts?
6. ### Physiotherapy job prospects?

Could you guys please elaborate? Why does it matter (to an extent)?
7. ### Physiotherapy job prospects?

How is it? When I graduate from a physio course from uni, will I be guaranteed a job or will I be stuck searching for one?
8. ### ATAR Estimate Please? :)

What a beast. 1v1 me pool. 99.55
9. ### HSC 2014 MX2 Marathon (archive)

Re: HSC 2014 4U Marathon Hello, I need help 3 letters, A B C. How many words can be made with n letters where A occurs zero or an even number of times. (n is an even positive integer)

o... yes... yes it is. thank you guys, I get it now.

What is 0 <= t <= 1 then? God I feel like I'm missing something very basic x_x

Right, so it starts at zero. If the question asked "find the velocity at the end of the 0th second", isn't t --> 1 ? So we sub in one?? :(

I'm just thinking, if the questions says "it initially starts at x=1...", t=0 is subbed in right? But initially means when it starts, so the beginning of 0 seconds, not the end of the 0th second.
14. ### Weird trig discrepancy?

I get it, thank you!

If the question asks "find the velocity at the end of 4 seconds", do we sub in t=4 or t=5?
16. ### Weird trig discrepancy?

Yep, I used general solutions. I get what you're saying, but does this mean my method is wrong as it doesn't have all the possible solutions? thanks :)
17. ### Weird trig discrepancy?

Does that mean my method is flawed somehow? If I change the cot x into tan(pi/2 - x), x=pi/2 comes out. What is the difference between these two methods and why does one have an extra solution?

bump
19. ### Weird trig discrepancy?

The problem is when I sub in x=pi/2 into tan2x=cotx, it yields true. However, when solving the tanx= +- 1/rt3, x=pi/2 is not one of the solutions. I am wondering why not. Thanks for replying :)
20. ### Weird trig discrepancy?

tan(2x)=cot(x) - Find the solutions of x for 0 <= x <= 2pi What I did was double angle for tan, and convert cot to 1/tanx Then solving for tan x from the quadratic, I got tanx = +- pi/6 + kpi However, when subbing x=pi/2 into the question, LHS=RHS but it is not one of the solutions from the...
