1. For A given below obtain 3A: 10 0 A = 0 10 0 01 2. For the matrices given below obtain A - B and A + B, where possible: 1 0 (a) A = 0 B = 001 1 0

This is my question from econ class. it's about matrix

1. For A given below obtain 3A:10 0A =0 100 012. For the matrices given below obtain A - B and A + B, where possible:10(a)A =0B =001102(b)A =B =11003. Perform the following matrix multiplications to obtain AB where possible: if(a)A-[8 8 1].09B =0243(5)B- [8 8 :].A =10124. Verify that (AB)? = BT AT:4(a)09B =2(b )11 3B =21 03015. Find the partial derivative of the following functions:a) f(r, y) = ry' +ry?b) f (r, y) = rytec) f(r, y) = Aryd) f(z, y) = 2rsin(ry)
