Students you can go to the playlist and watch all my videos as here the complete playlist is arranged topic wise so you all won't face any problem as many students complain that sir we are not getting this topic that topic so here here everything is topic wise arranged in the playlist so you can go and watch my videos Hello students myself Dr. Gajendra Purohit and today I will start solution of the simultaneous equation or the algebraic equation by the help of that like how we solve equations from the numerical method that I will tell you. Students there are two types of method one is direct method and other one is indirect method in direct method we have gauss elimination method gauss jordan method, matrix inversion method partition method as there are two three types of methods and then in indirect method we have jacobi method and gauss-seidel method and there are more methods also which are the intrusive methods where we have to apply the intrusions and in direct method we can directly find the solution of the question. OK? so first I am telling you gauss elimination method. Students gauss elimination method and gauss jordan method both are almost the same but there is just some difference that I will tell you today that what is the difference. Let's first do this question solve the following equation by the help of the gauss elimination method so students let me tell you that on numerical methods I have already uploaded a lot of videos like newton raphson, bisection regula falsi, secant method iterative method, interpolation and then like numerical integration, numerical differentiation all the videos of these are on the I icon and are uploaded so you can go and watch them plus students ring of matrix topic is there please do watch that topic as it will help here in understanding the gauss elimination method but I will tell you, but if you understand that it will be better so that also you can see by going on the I icon so this question is given, first we will keep this in matrix form so this is how we solve this question by this method I will take one more question where I will apply gauss elimination and gauss jordan also so that you know the difference between the two that what is the difference between gauss elimination and gauss jordan so students let see the next question so students see here the question solve the system of equation this,this,this by using gauss elimination method and gauss jordan method so first I will tell you this question by gauss elimination and then with gauss jordan method , by both we will get the same answer This is how we solve question with gauss elimination method. Students now I will tell you how gauss jordan method is applied here so we will do this equation with gauss jordan method so this is how we apply gauss jordan method. Students gauss jordan method and gauss elimination method you must have understood this. What we do in gauss elimination method is like me make 0 here and then we will make 0 here in gauss jordan method three 0 are made here three are made there which means in gauss elimination method we convert in upper triangular method in gauss jordan method we convert in diagonal matrix ultimately we get the same answer from both of them there is no change. So this is how we solve the question students the numerical method for this this topic you must have understood. Students after this I will take indirect method where we have jacobi method gauss-seidel method and I will discuss all of these so students be with me and on all these topics whatever questions are possible in the competitive exams on that I am taking live classes so you can go and attend my live classes and if you have any doubt then please comment and I also have my whatsApp group for that I will send you the link and I have my number on that you can whatsApp message me so that I will add you in the group as we discuss a lot of things plus for books also we share many links and we share many more thing so in the group to add yourself in the group you can be added to my whatsApp group so students thank you.
