On my channel here, you will get flavours on topics in Mathematics. I have been into teaching line from past 11 years and currently I am teaching to Engineering Students. So you can mostly relate my contents to what Engineers learn mathematics during their Engineering.

Sir I want one answer,in my book ([(2,1,0),(1,3,0),(0,0,2)]) symmetric matrix and its gn eigen value is 1,2,4 eigen vector (1,0,-1),(0,1,1),(0,1,0),but oi check it was wrong,so please send correct matrix for that sir,i want to know what is wrong in that Matrix
@DrMathaholic
@DrMathaholic 8 дней назад
In this case , you P matrix will be first 3 columns and Diagonal matrix D will be 1,2,4 as the diagonal entries. Then P DP inverse will give us the matrix A... make sure to maintain the order of eigenvalues and eigenvectors.. I will try to do the calculations once I get free time..

@DrMathaholic
@DrMathaholic 7 дней назад
Once we r done with finding the limit for inner integral, we go to outer integral. For limits of outer integral, we project the region on that axis. Here we are projecting the upper triangle, which I called R1, onto the y axis, and we can see that when we project upper triangle R1 onto y axis, y will go from 2 to 4.
