Unformatted text preview: a. y = 30 b. s = t 100 3. Power in general is true for powers that are all real numbers (we’ll be able to prove this later) 4. From our “Limit Laws” (reference 2.3 page 108 in the text) we have “constant multiple” rule for derivatives d dx cf ( x ) = “sum and difference” rule for derivatives d dx ( f g ) = Lots of examples using the rules: 5. Derivatives of exponential functions f ( x ) = c x Write down the derivative using the definition: More examples using the derivatives of both polynomial and exponential functions....
