The main idea was to use the laws of logarithms and then some multiplication and division. It was a good problem to wreslte with for any 12th-grade student.

Position, Jerk, Pop and Other Derivatives of The Position Function

Whenever we discuss motion, we often talk about position, velocity and acceleration. in this video, i introduced the audience to higher derivatives of the position function such as the jerk, which is the change in acceleration with time. Other derivatives were the snap/jounce, crackle and the pop.

Third International Mathematics Olympiad #2
zhlédnutí 8KPřed 14 dny
This problem is from the third IMO held in Hungary 1961. I found it relatively easy compared to other problems I see these days. It required a basic knowledge of triangle areas, binomial expansion, and inequalities. For the second part of the problem, a=b also means a=b=c since a,b were chosen arbitrarily. so it's an equilateral triangle.
Find the last digit of (1! + 2! +...+ 1982!)^1982
zhlédnutí 10KPřed 14 dny
For last digit problems, it is expected to focus the computation on the last digit of the base. 5! and other bigger factorials have last digit zero. So the lkast digit of the base is determined by the first four factorials in the sum.

    answer is 16, a power tower of 2's stacked 3 high. Graham's number (G64) has its origins from a massive power tower of 3's i believe.

  • @Mathematical-Mind
    @Mathematical-Mind Před dnem

    We can have 9 to the power of the first equation, 16 to the power of the second equation, and 25 to the power of the third equation. It’s an alternative solution and may be simpler to understand.

  • @benjaminangulo8326

    you used a logarithm to make x^(x-3)=1 a logarithmic ecuation, and the argument of a logarithm is DEFINED as positive, so you should have restricted x to x^(x-3)>0, that's it a simple explanation, then , you can say, x^(x-3)<0, so you multiply everything for -1 and THEN convert it to a logarithmic ecuation.

  • @programmingpi314
    @programmingpi314 Před dnem

    I love that our video are easy enough that I can always work out the problem myself first, but not so simple that it feels trivial. As for my solution to this problem, it started out the same (excet I didn't show (1,1,0) was a solution until the end) up to the point where you show that x^2-2x+1+z^2=0. Originally I was going to use the quadratic formula like you did, but I noticed that it's just a sum of squares: (x-1)^2+z^2=0. Because a real number can't square to give a negative, both (x-1) and z have to be 0. The solution is then obvious from there.

    I think the "trick" is to recognize that multiplying them all together leads to a nice equation where both sides are 4th powers, and then you can quickly make progress. I spent a lot of time trying to add and subtract and factor before watching the video, and it just took so long to get anywhere. But if you multiply everything it simplifies nicely.

    Step 1: Make the base the same for each equation: log9 x + log9 y + log9 z² =2 log16 x + log16 y² + log16 z = 1 log25 x² + log25 y + log25 z = 0 Step 2: Combine logarithms using log x + log y = log xy: log9 xyz² = 2 log16 xy²z = 1 log25 x²yz = 0 Step 3: Remove logarithms using logb x = y => x = b^y: xyz² = 9^2 = 81..................(1) xy²z = 16^1 = 16................(2) x²yz = 25^0 = 1...................(3) Step 4: solve for y using the equation (3): y = 1/(x²z)..............(4) Step 5: Substitute y = 1/(x²z) into equation (1) and solve for z: z = 81x................(5) Step 6: Substitute this to equation (4): y = 1/(81x³).............(6) Step 7: Substitute y = 1/(81x³) and z = 81x to equation (2): x * 1/(81x³)² * 81x = 16 => x^4 = 1/(81*16) => x = 1/(3*2) = 1/6. Solution x = -1/6 won't do. All x, y and z must be positive because otherwise the logarithms aren't defined. Step 8: Calculate y and z using (5) and (6): x = 1/6 y = 8/3 z = 27/2 Checking these with the second equations indicates correct values.

    With proper factoring, you get the linear equation Ma=b where M is the matrix [[1 1 2][1 2 1][2 1 1]] (all ones except the off diagonal), 'a' is the vector [log(x) log(y) log(z)], and b is the vector [log(81) log(16) log(1)]. Computing the inverse matrix and solving for 'a' gives you that a=[log(1/6) log(8/3) log(27/2)], thus the arguments of the logs in 'a' are the values for x,y, and z.
