    Geometric/arithmetic question

    For a start, this is 2 unit, not 4. 97% of the light gets through the first sheet. 97% of THAT transmitted light gets through the second sheet. So 0.97^2 of the light incident on the first sheet gets through the two sheets. Following this through, if there are n sheets then the fraction of...

    What is everyone doing these holidays?

    Your HSC is in 2019. Call it 'procrastinating' in two years time. Right now it is called 'enjoying your holidays'.

    Simpson's rule

    Assuming you've learned the h/3 version of Simpson's rule: h=(2-1)/4 = 1/4 So the x-values used are 1, 1.25, 1.5, 1.75, 2 So the y-values used are 1, 4/5, 2/3, 4/7, 1/2 So the approximate value of the integral is: (1/4)/3 [1 + 1/2 + 4 (4/5 + 4/7) + 2(2/3) ]

    Probability

    You don't need so much combinatorics. If you assign the positions of letters in the word numbers 1 to 7, and you don't care about the order of N and T, the number of ways of choosing the order of those letters is 7C2 = 21. The number of ways of choosing these letters with 5 letters...

    Why do they give us such little time for exams?

    I agree that the exam system is not ideal, and creates a production line mentality. That is why they are bringing alternative assessments into the new syllabus.

    HSC 2016 MX2 Combinatorics Marathon (archive)

    Re: HSC 2016 MX2 Combinatorics Marathon As an aside, this question won't prove that you have found the minimal solution, merely that the formula works for your method. There is an interesting graph which shows that the method is the optimal solution by noting that the shortest path between...

    Maximum of three normals pass through point inside parabola proof

    The equation of the normal is cubic in t. Hence it has up to three real roots (dependent on the value of the point [x,y] you substitute into the normal equation), each root (value of t) corresponding to a point on the parabola.

    Actually the vaccines have been proven NOT to cause autism. I think you are reading the same type of article you suggested Drsoccerball was reading. Half a million children were tested in Denmark, and the study found that unvaccinated and vaccinated children were equally likely to acquire...
