1. Create a row vector that has the following elements: 3.4, -2.55, 68/16, 45/110, cos(25), and 0.05.
2. Define the variables x = 0.85, y = 12.5, and then use them to create a column vector that has the following elements: y, y, In(y/x), y-x, and x+y.
3. Create a row vector in which the first element is 2 and the last element is 37, with an increment of 5 between the elements: 2, 7, 12, ..., 37.
4. Create a row vector with 9 equally spaced elements in which the first element is 81 and the last element is 12.
5. Create the following matrix by using vector notation for creating vectors with constant spacing and/or the linspace command. Do not type individual elements explicitly:
10 15 20 25
30 50 9 400
300 200 100 0
0.8333 1.6667 2.5 3.3333
4.1667 5
6. Create the following matrix by using vector notation for creating vectors with constant spacing and/or the linspace command. Do not type individual elements explicitly:
50 3
