El problema 3 no es la D? Por que tengo un libro de ese problema y tiene su tabla de respuestas y en la tabla dice que la 3 es la D

🎯 Key points for quick navigation: 00:00 *Introduction to matrices and determinants in algebra, highlighting their frequent use in vector products.* 00:28 *Definition of a matrix as a rectangular arrangement of elements in rows and columns; matrices are typically denoted by uppercase letters.* 01:23 *Explanation of matrix order, given by the number of rows (m) and columns (n). For example, matrix A is a 2x3 matrix.* 02:46 *Matrices A and B are described by their order; A is 2x3 and B is 3x3, based on their rows and columns.* 03:43 *The concept of matrix elements is introduced, including how to denote specific elements within a matrix, such as a_11 for the element in the first row and column.* 05:16 *Different types of matrices are defined, including row matrices, column matrices, rectangular matrices, square matrices, and the null matrix.* 09:25 *Operations with matrices include addition, subtraction, and scalar multiplication. Matrix subtraction is defined similarly to addition but involves multiplying one matrix by -1.* 12:41 *To add matrices, they must have the same order. Each corresponding element is summed to find the resulting matrix.* 15:29 *Scalar multiplication affects all elements of a matrix; for example, multiplying matrix A by 2 results in each element being doubled.* 17:20 *Conditions for matrix multiplication are explained: the number of columns of the first matrix must equal the number of rows of the second matrix.* 18:39 *An example is given to demonstrate matrix multiplication, detailing how to multiply a row from the first matrix by a column from the second to get the resulting matrix elements.* 21:19 *In matrix multiplication, the number of columns in the first matrix must equal the number of rows in the second matrix for the product to exist.* 23:10 *The product B x A does not exist if the number of columns in B does not match the number of rows in A.* 24:06 *Multiplication of matrices involves row-by-column operations, and raising a matrix to a power follows similar logic to number exponentiation.* 26:12 *The element-wise square of a matrix is not simply the square of each individual element.* 26:55 *The distributive property applies to the multiplication of a scalar and the sum of matrices: k(A + B) = kA + kB.* 27:09 *Matrix multiplication is not commutative; A x B is not the same as B x A.* 28:18 *The associative property of matrix multiplication allows for different groupings when multiplying multiple matrices.* 31:29 *Transposing a matrix involves converting all rows into columns, effectively inverting its dimensions.* 35:31 *Double transposing a matrix returns it to its original form.* 36:25 *The transpose of a product of two matrices is the product of their transposes in reverse order: (A x B)ᵀ = Bᵀ x Aᵀ.* 37:18 *The trace of a square matrix is the sum of the elements on its main diagonal.* 40:02 *The trace of a product of two matrices is invariant under permutation, i.e., tr(A x B) = tr(B x A) when they're both square matrices.* 42:08 *Determinants transform a square matrix into a real scalar. The determinant of a 2x2 matrix can be calculated by multiplying the elements of the principal diagonal and subtracting the product of the elements of the secondary diagonal.* 44:24 *For 3x3 matrices, the determinant can be calculated using cofactor expansion along the first row. This method involves multiplying the elements by the determinant of the smaller 2x2 matrices obtained by deleting the row and column of each element.* 49:13 *Van der Monde determinants are special cases often used to reduce complex calculations, such as finding inverse matrices or solving certain types of problems efficiently.* 51:00 *A square matrix is non-singular if its determinant is not zero, and singular if its determinant is zero.* 53:12 *To solve a 3x4 matrix problem where each element is given by a formula involving its position, identify matrix elements based on additives if indices match, and differences if they don't, then sum the elements according to the problem's requirements.* 59:11 *The product of two matrices involves multiplying corresponding elements and summing the results across the rows and columns. This is used to solve linear equations by setting products equal to given values.* 01:03:22 *When given matrix elements as linear equations, solve the system of equations to find the variable values. This involves standard algebraic methods such as substitution or elimination for solving simultaneous equations.* 01:04:07 *Solving matrix determinant problems by identifying equal determinants and calculating using matrix operations.* 01:07:15 *Using cofactor expansion or Charro's method to compute determinants; both methods yield the same result.* 01:08:14 *Introduces a system of replicating columns to solve determinant problems using sequential calculations.* 01:09:51 *Calculation of determinant continues with specific multiplication and addition steps for each element.* 01:12:27 *Outlines the subtraction of products from the opposing diagonals to find the determinant's final value.* 01:14:05 *Summarizes the result for the determinant, stating a solution of 0.5 with implications for further mathematical proofs.* 01:14:21 *Encouragement to share educational videos and appreciation for the class participants.* Made with HARPA AI

Profe gey

Tan gozuu profe

Que bueno

Le falta humildad profe V:

cachimbo es una forma de burla.

No aprendi solo vine a copiar la tarea 😔

Profesor tengo una duda por qué divide 3 en la penúltima operación en el último ejercicio.

El problema 3 la diagonal no es bisectriz salvo que me digan es un cuadrado o un rombo, ya que dicen que es un paralelogramo. Pero si sale 6 como respuesta.

47:31 no era +-+ con los signos? 😊

7x8= 56 56+4 =60

49 + 16 = 65 NO 55

Está mal tu problema donde aplicando sarrus sale 64 y no 50. Tenías que haber puesto antes de aplicar menores complementarios los signos intercalados + - + y con eso si sale 64 y problema corregido.

❤

Estimado profesor no queda claro la suma de números naturales consecutivos. Agradeceré si ud lo puede explicar con manzanitas.

La cuatro no está mal

1:04:36 :vhola ,yo lo resolvi tengo una duda porque me salio 30 ya que x pb seria x y del equilatero seria 60+x es igual a 90 y x saldria 30

Muito bom !

cuando es impar hay un central y cuando es par hay dos centrales!!!!!!!

Excelente profee❤

cool xd

Muchas gracias profesor 🧡

Volumen muy bajo

profe en el final no sale 6????

Debería hacer en un espacio más grande para que entiendan mejor 🧐

Profe es un chucha merece más espectadores csmre

Gracias profe , dónde encuentro más material

chiquitis

😎

en el problema 10 no hay clave, pero tampoco así se debe mostrar la respuesta

esos precozes del video xD

sin quitar el 5

hermano la clave es la A)

oye amigo me puedes ayudar con un trabajo de determinante con la matiz esque no entendí

Saludos profesor excelente tutoria,quisiera saber si con estas formulas puede resolver una duda que tengo,y es que quisiera saber como se calcula la fuerza o velocidad tangencial que se necesia para que una persona salga disparada en un rueda giratoria de un parque infantil?,como hay videos de personas saliendo disparadas cuando le ponen una goma de motor girando que ayude a acelerar las revoluciones de la rueda giratoria.

excelente clase, gracias!!!

LA EXPLICACIÓN ESTA MUY BUENA PROFE :) ...... AHORA SI YA ME QUEDO MUY CLARO SOBRE LAS MATRICES 😀

La negación de algunos no son seria todos son creo que hubo un error en la parte teórica

Profe un aduda, es sobre el problema 4, ¿No se supone que el 4 y el 2 del denominador se multiplican y este resultado de multiplica por 13?

El mejor profe, para mi excelente explicación

Halla el producto de abc por 248,sabiendo que el producto de sus productos parciales es 900 al cubo ayuda

Muchas gracias!!!!!!!!!!!

Muchas gracias por el video :3

👍👍👍

Pregunta 6 es de admision

profe en el ultimo problema al considerarlo un solo cuerpo como dice el peso ya no seria 120 sino 240 entonces la normal saldría diferente por que sigue considerándolo con 120 si a unido supuestamente ambos cuerpo ?

Esta clase está genial, explican bien. Gracias academia Giga 💯

Gracias, fue muy últil el video. :D

debes mejorar tu audio un poco nomas profe
