Elementary Row Operations
In this video, we'll dive into the three essential elementary row operations in matrix algebra. I'll break down each operation-row swapping, row multiplication, and row addition/subtraction. After explaining each concept, I’ll demonstrate an example using a 4x3 matrix of real numbers, showing exactly how these operations can be applied step-by-step. By the end, you'll be able to perform elementary row operations confidently!

help me to solve this question: A bus on line A arrives at a bus station every 4 minutes and a bus on line B every 6 minutes. The time interval between an arrival of a bus for line A and a bus for line B is uniformly distributed between 0 and 4 minutes. Find the probability: a) That the first bus that arrives will be for line A. b) That a bus will arrive within 2 minutes (for line A or B).
Yes for sure, I will help you. This evening I will make a video of how to solve this problem. Besides the concept of uniform distribution, you know integration, am I right?
I have posted a solution to this question in ua-cam.com/video/w-eV621AorY/v-deo.html

Good to know from one of my number one subscribers 👍
It's very clear! Thank you so much
I’m glad you have found it useful. Please feel free of ask any question in the comments.
My problem is that I don't know how to use the formula in the calculator to arrive at the final answer.
Hi Bashiru, Thanks for your interest. I understand your problem. Every calculator is different but every scientific or financial calculator has a key for the exponential function. You can see the following video in which I explain how to use that ba II + calculator of Texas instrument for solving a similar problem: ua-cam.com/video/NtmBrDzoKRI/v-deo.html. This is a long video, but the explanation of the calculator is from about minute 18

Ratio + does not work
Thanks for sharing. If the function does not have indetermination, just make a substitution, example g(1). If the function is a ratio with an indetermination 0/0, as the one in the example, you cannot make the substitution. So, you will need to use the graph of the function and click on the point of the graph that has x coordinate given by the value x approaches.
another great lecture
Glad you think so!
great lecture
I’m really glad you like it
it really helped me in my final exam @@aplusintegral
great explanation, thank you so much, specially, I understood the difference between mu and lambda
You are really welcome! Yes, I have followed the notation of some textbooks (Groebner's textbook from Pearson for example) that show the difference between the average (lambda) in the segment of the information of the question, and the average (mu) in the interval of the actual question of the problem. Some other classical textbooks only consider in their explanation the average in the actual question of the problem, and for them, mu and lambda are the same thing. So we need to be careful what type of notation your book is using. Thanks a lot for your participation.
Thank you so much for your time giving further information. good day Sir @@aplusintegral
Muchas gracias Profesor. por la tan detallada explicación. Sin embargo. me pregunto si podrías extenderte en la contribución de Cantor o si esta esta restringida exclusivamente a la creación de la Teoría de Conjuntos.
Hola Adrianmonk, gracias por tu pregunta y por tu interés en el tema. Por supuesto una vez la teoría de conjunto entra en escena el concepto que ahora conocemos como función queda casi por completo determinado. En efecto Cantor lo utiliza en definiciones y demostraciones. Por ejemplo en la sección 4 del artículo de 1895 "Contribuciones a los fundamentos de la teoría de números transfinitos" Cantor define la operación exponenciación entre números naturales n^m, como el número de posible funciones (el llama a las funciones "cubiertas" del primer conjunto), entre un conjunto que contiene m elementos y otro que tiene n elementos. Incluso, en este artículo, Cantor llama función de x y denomina f(x) a lo que nosotros conocemos como imagen de x.
Gracias, Información recibida@@aplusintegral
Your very welcome. Please feel free to ask any question related to this topics@@adrianmonk4468
Muchas gracias por este vídeo. Siento que me va a ayudar en mi preparacion para mi examen.
Me alegra mucho que lo hayas encontrado útil.
Excelente video. Excelente pedagogía: enuncia el concepto, lo parafrasea, lo ilustra con ejemplos sencillos, define los elementos usados en la definición, aplica el concepto, repite para ayudar a memorizar, etc. Muestra las fuentes originales y en distintas lenguas: ésta es la labor de un académico serio. Se pueden leer las notas fácilmente mediante el uso del acercamiento de la cámara. El volumen del audio es adecuado, y mejoró hacia el final. Felicitaciones: me quito el sombrero..
Muchisimas gracias. Comentarios como este me invitan a seguir en esta labor.
How e^-5?
Thanks for your question. I understand that your question is how to compute e^-5. Well e=2.7182818, approximately. So, one way to compute this will be using this approximation in your calculator and use minus 5 as the exponent. However, every Financial and Scientific calculator has a key for the exponential function (e^x) you can use this function of your calculator. If you want to know more about the number e, you can see my video: ua-cam.com/video/6ShLN8B8xDs/v-deo.html

Hi sir, ur video makes me so motivate to learn this material. But can I ask, why when we find question c we should put 1 in cumulative part in excel? Thank u
Hi Alifia, Thanks for your words. Any time that we want to compute a probability of the form, P(X<=a) (with a less than or equal to), we need to inform Excel that this is a problem of cumulative probability. For doing that we can type in Excel, as final argument, "TRUE", or a 1, that has the same meaning in Excel. With this, we inform Excel that is true that this is a cumulative probability. If the problem is an exact probability, that is to say is of the form P(x=a), then we need to inform Excel that it is not cumulative typing as a final argument "FALSE" or a 0. If you have further questions, do not hesitate in asking us. Thanks again
Thanks!
Your really welcome Adrian :)
The formula for the crash multiple is: ∞/(∞-X), X is randomly selected from 0~∞. The data are 6.51 and 9.51 The result is = 33.88 Can you explain to me how to find this result please Can you give me a solution to this issue
Hello MM-ys4fx, Could you provide more information about the context of your question. I will be very happy helping you and providing a video explaining. However, I will need more information. What is the topic? What do you mean when you say "crash multiple"? What is the subject you are studying?
@@aplusintegral I am not good at English but I am a moment that the responsibility is giving a number and predicting the result The Data Are 6.51 and 9.51 The Result Is = 33.88 The result is the number of prediction I want it because I discovered that one of the games are going on this pattern
@@MM-ys4fx I still want to help you. however I do not understand exactly what Is the actual question. If you want, you can write the whole question in your mother tongue ( if is taking from a book, type exactly as it is), and I will try to translate using a digital translator.

Thanks so much. Do you do statistics tutoring as well?

What is the value of e
e is approximately 2.7182818285. It is la base of natural logarithms. Every scientific calculator has a function to compute its powers, e^x. In this channel there is a video showing deduced to how this constant can be obtained here it is the link ua-cam.com/video/6ShLN8B8xDs/v-deo.html
