 Hello friends, welcome to the session I am Alka we are going to discuss matrices. We have to add the two given matrices our first matrix is cos square x sin square x sin square x cos square x and our second matrix is Sin square x cos square x cos square x and sin square x now let's start with the solution We like the corresponding elements of the given matrices. This will give us cos square x plus Sin square x and this sin square x plus cos square x then sin square x plus cos square x and cos square x plus sin square x Now as we all know that sin square theta plus cos square theta equal to 1 Therefore in place of cos square x plus sin square x we can write 1 We get 1 1 1 1 as the resultant matrix. So This is a required answer. Hope you understood it and enjoyed the session. Goodbye and take you
