Need last minute tutoring for HSC? Preparing ahead for HSC next year?

I am currently a third year science student majoring in (pure) maths. I am willing to tutor all levels of high school maths. I completed the HSC in 2004 and achieved 94 in both ext 1 and 2 maths. In addition I've also achieved, as a student, bronze in the 2004 Australian Maths Olympiad and invitation to National Maths Summer School in 2004 and 2005.

As a tutor, I have been working as a mentor in the AMOC Correspondence Program since 2005, having guided numerous students in the program to gold and silver in the AMO. I have lectured to high school students on maths at AMOC schools, and have been tutoring at National Maths Summer School since 2007.

In addition, I have ample experience in private tutoring, having tutored no less than 10 students in the past 12 months, with a significant improvement in results for almost all students.

I am willing to tutor around the Inner West and around Camperdown (I am willing to travel a bit), and I charge $35/hour. Please PM me if you're interested or need more details.

If you think you're good at maths then do this question

Find the point on the straight line 2x + 3y = 6 which is closest to the origin.

I personally don't see what's the point of posting that, but anyway:

This point will be connected to the origin by a line perpendicular to the given line. So all you need to do is find that perpendicular line and solve for (x,y), which turns out to be (12/13, 18/13)

hey yinan,

who are the tutors at NMSS 08? and the EG tutor?

btw ppl looking for a tutor, this guy's pretty good at maths.

Yinan, you still look exactly the same as you did 4 years ago lol.

Biography should get to you soon. As for the EG tutor, your guess is as good as mine.

If you think you're good at maths then do this question

Find the point on the straight line 2x + 3y = 6 which is closest to the origin.

If you mean intiger point:

2x + 3y = 6
2x + 3y = 6 (mod 3 )
2x = 6 (mod 3)
2 and 3 are coprimes
x = 3 (mod 3), y = 0

or


2x + 3y = 6 (mod 2 )
3y = 6 (mod 2)
2 and 3 are coprimes
y = 2 (mod 2)
x = 0

The closest intiger point is (0,2)

If you mean the closest real point:

Consider the two equations

2a + 3b -6 = 0
2c + 3d -6 =0

2(a-c) + 3(b-d) = 0
But this is equivilent to the dot product of the vectors (2 3) and (a-c b-d)

as the dot product equals zero, the vector (2 3) is perpendicular to the vector (a-c b-d) which runs along the given line.

Therefore the line y = 1.5x pass through the origon and is perpendicular to
2x + 3y = 6

Solving these two equations simultaneously gives the point (12/13 , 18/13).

This point will be connected to the origin by a line perpendicular to the given line. So all you need to do is find that perpendicular line and solve for (x,y), which turns out to be (12/13, 18/13).

Correct

What is the thickness of a thin film (n = 1.58) when it is put over one slit of a double slit arrangement with light wavelength = 550nm incident to it. On an adjacent viewing screen, the 7th order bright fringe appears in the center.
