    It looks like there is a slight mistake at 29:01, the -10 changes to zero during the R3+R4->R4 operation when it shouldn't. So I think parametric form should look like: x1 = x5 - x3 x2 = x3 - x5 + 10 x3 is free x4 = 10 - x5 x5 is free

    Why is matrix multiplication defined this way? 😮

    • @carultch
      @carultch 4 หลายเดือนก่อน

      Good question. Consider its application in solving systems of linear equations. First, consider an equation of 1 variable, suppose 3*x = 12. To solve this, you multiply both sides by the reciprocal of 3, so that 1/3 * 3 = 1, and you isolate the x. Now you have x=12/3, which is 4. Now consider the higher dimensional systems of equations, and you'll see it is very similar. You construct a matrix equation of a similar form, A*X = B, where A is your square matrix of coefficients, X is your column matrix of variables, and B is your column matrix of RHS constants. To solve this, you left-multiply both sides by the "reciprocal" of matrix A (technically called a multiplicative inverse). This turns A^(-1) * A into the identity matrix, that when multiplied by matrix X, generates X itself. Now we've isolated matrix X, and the remaining product of A^(-1)*B tells you its values. So for a generalized 2x2 example, we'd like to turn the equation: a*x + b*y = e c*x + d*y = f Into A*X = B Where: A =[ a _ b ] _ _ [ c _ d ] X = column matrix [x, y] B = column matrix [e, f] Carry out the matrix multiplication of A*X, rows of A dot product with columns of X, and we get the following column matrix: [ a*x + b*y ] [ c*x + d*y ] Which we can equate to matrix B. As you can see this gives the original system of equations.

    It turns out that in this example partial fraction decomposition provides a simpler path to the solution without the need for an algebraic "trick". Just to be clear, I'm not slamming this approach but this only works if you see the trick. Partial fractions always works but it is not always simpler.

    Are there practical applications for complex trigonometric functions? I have seen complex numbers used for solving polynomials, analyzing circuits, and harmonic motion; but I've never needed to take the cosine of a complex number.
