00:00Here we have a matrix which is a matrix which is a matrix
00:03and we will ask theta which is a plus a transpose identity matrix
00:10which is order 2
00:12order 2 is a identity matrix
00:161 1 0 0
00:17we will know that this is a identity matrix
00:20we will simply solve this value
00:22so we have a transpose
00:25then a transpose
00:27what is the transpose?
00:29row becomes column
00:30and column becomes row
00:33for example first row
00:35cos theta minus sin theta
00:37what will be the first column
00:39cos theta will be the first column
00:43cos theta will be the first column
00:44because this row is the first column
00:45as it is second row
00:48cos theta is the second column
00:49cos theta is equal to identity matrix
00:551 1 0 0
00:56now we will know that the matrix matrix is directly add
01:00the elements are corresponding elements
01:02cos theta plus cos theta
01:052 cos theta
01:06sin theta minus sin theta 0
01:11cos theta plus cos theta
01:13cos theta plus cos theta
01:14cos theta is equal to this
01:21cos theta
01:22cos theta is equal to this
01:27cos theta
01:28cos theta
01:29cos theta
01:36so
01:36it
