1 - Derivative of a constant function.
The derivative of f(x) = c where c is a constant is given by
f '(x) = 0
Example
f(x) = - 10 , then f '(x) = 0
2 - Derivative of a power function (power rule).
The derivative of f(x) = x r where r is a constant real n

Read Section 2.1 and 2.2 of the text up to the section titled, Linear Systems over Z p (page77).
1.) Is the row echelon form of a matrix unique? If so, why? If not, give an example to show two
different row echelon forms of a matrix.
