    Why we are not dealing with e2 means why we not do e2^T.[cov matrix]

    Here, we had considered 2 dimension as the high dimensonal data for example. One of the most usecase of PCA is in dimensionality reduction. So, if you want you can use e2 and get second PC. But then think about it. From 2 variable, we again got 2 variables. That's why he has shown only PC1. However, in reality we generally use 2 PC axes (mostly depends on your data). If it has a lot of variables, then 3 or 4 can also be good but we don't generally go beyond that. So, in this case you will need e2, e3 and e4 as well. So this is how it works.

    Hi Sir, Great explanation about PCA. But when I searched the covariance matrix for more 2 variables it's showing that covariance is only done between 2 variables. How to calculate the covariance if a dataset have more than 2 variables. Could you please give an explanation on that.....!!

    @fintech1378 is right. You need to do pairwise combinations. For example, for 4 variables, your covariance matrix will be 4x4 with the following combinations: cov(a, a) cov (a, b) cov (a, c) cov(a,d) cov(b, a) cov(b, b) cov(b, c) cov(b, d) cov(c, a) cov (c, b) cov(c, c) cov(c, d) cov(d, a) cov(d, b) cov (d, c) cov(d, d)
