Hello sir! Thank you very much for your hard work. I appreciate it. And your technique of teaching is amazing. So please never give up on your hard work.
i miss this math so much. I ended up not taking higher level math when i got to college despite taking calc3 and diff eq in highschool. it is something i regret because while i know i had the capability to do this i dont any more. I miss this so much. Thank you for reminding me of my love.
On algebra class for IT which i have we have rank of the matrix before solving systems of equations 1. Check if solution exist With rank of the matrix we can easily determine if system of equations has a solution 2. Reduce system of equations to Cramer form Cramer's form is when coefficient matrix is nonsingular I we know the rank of the matrix we can choose submatrix of the coefficients matrix size rxr where r is the rank of A and this submatrix will be invertible 3. Solve system of equations in the Cramer form In step 3 we can use Cramer's rule or matrix inverse In first two steps rank of the matrix is useful Yes you will explain row echelon forms here ant it is ok x+1 = x + 2 x seems to be infinity but it is not a number
If det equal to 0, it does not mean that there is no solution. It mean there is no unique solution. It mean that there is no solution or there is multiple solution
I may forget it but you dont forget about linear transformations and things like kernel later in your algebra video series I like that you record this video series step by step from the begining Do you plan to record something like that for numerical methods in the future
@@PrimeNewtons You will make it When you finish algebra video series you can go to the library borrow some books like Kincaid, Cheney Numerical Analysis and make the notes

thats how i need my maths teacher to be , appaluse for ur work , always pls upload this kind of maths vedio

Thank you sir 🙏🙏...I am from India..
thank you very much. this makes my brain feel better.

1. Check if solution exist
With rank of the matrix we can easily determine if system of equations has a solution
2. Reduce system of equations to Cramer form
Cramer's form is when coefficient matrix is nonsingular
I we know the rank of the matrix we can choose submatrix of the coefficients matrix
size rxr where r is the rank of A and this submatrix will be invertible
3. Solve system of equations in the Cramer form
In step 3 we can use Cramer's rule or matrix inverse
In first two steps rank of the matrix is useful
Yes you will explain row echelon forms here ant it is ok
x+1 = x + 2
x seems to be infinity but it is not a number
There is nothing inconsistent about Prime Newtons. He is consistently a cut above! 🎉😊
Great🎉
i paused it and used the inverse formula. found the determinant to be zero, that's how i knew it was not invertible
If det equal to 0, it does not mean that there is no solution. It mean there is no unique solution. It mean that there is no solution or there is multiple solution
determinant = 0 means that there is no solution or there is more than one solution.. so not always just no solution.

If I'm smart enough, I'll make videos for Numerical Methods 😀. Thank you.

Adding the 1st equation to the 2nd gives you the same thing as the 3rd equation, giving you 3=1+0, which is impossible.
thanks
