Exercise 4.2 In this exercise we are going to work with the following matrix 002 0.001 o ] N=11 0.01 0 0 00.025 Use det to compute the determinant of N100. Do you think that N100 is invertible? Also use the command to compute the determinant of N. Now, using the determinant of N as a known quantity, calculate by hand the determinant of N100 Would you now reconsider your answer to the previous question? Explain. Hint: look at Remark 4.1 and consider some of the properties of determinants
