How to integrate using substitution
Просмотров 16Год назад
In this video we take a look at an example to illustrate how one can use substitution to solve integrals. Substitution is an integration technique that is the opposite of using the chain rule for differentiation. We will have lots more integrals coming up demonstrating the technique.

    what do you look for when you're trying to figure out if you need to use sine rule or cosine rule

    • @sbmathsyt5306
      @sbmathsyt5306 9 месяцев назад

      For the sine rule you need two sides and two angles. That could be 2 known sides, one known angle and an unknown angle that you are trying to find for example. For the cosine rule we require 3 sides and 1 angle

    You could've made this actually educational by explaining the process out-loud. Or writing out a formula that can be used to reach the solution. To someone who doesn't know matrices, they have no clue what you're writing.

  • @pocok5000
    @pocok5000 Год назад

    x(x+1) is a product of two consecutive integers, one of which is even. If this was meant to be a demonstration of the method, you should use an example where that's the easiest method.

    • @sbmathsyt5306

      Fair comment. With a simple example like this there are lots of ways to go about it, wanted to pick an example where the method could be easily applied. Thanks for watching and commenting :))

    A number always keeps its parity when squared and adding numbers of the same parity always yields an even number

  • @arielyahav4497
    @arielyahav4497 Год назад

    Or if you write x = 2k + m, m being either 1 or 0, the proof devolves into pricing the same claim for m, namely m squared plus m is even, but now m is either 0 or 1.

  • @Googl81
    @Googl81 Год назад

    If you factorise the x^2 + x as x(x + 1) first, it becomes much easier to solve. Case 1: x is even => 2(k(2k + 1)) Case 2: x is odd => (2k + 1)(2k + 1 + 1) = 2((2k +1)(k + 1))

      @sbmathsyt5306 Год назад

      A matrix is simply an array of numbers. For matrices which are square (have the same number of rows and columns) we can find a quantity called the determinant, which is demonstrated here for a 2x2 matrix.

    What if I assumed that the gcd between a and b, is 2 , I will never change any thing in the proof, I mean can you assume what ever you want and just building on it?!!

    • @sbmathsyt5306
      @sbmathsyt5306 Год назад

      The idea of proof by contradiction is make an assumption and then get something back that is incorrect using operations we are allowed to use. Then we know that the assumption must be incorrect. If we assume the gcd(a,b)=2 then we have a=2m and b=2n. Then we could consider m and n which must then have gcd 1 and could do the exact same proof
