- Do this question: Fill in the blanks so that the argument in part (b) has the same logical form as the argument in part a: a. If n is divisible by 6, then n is divisible by 3. If n is divisible by 3, then the sum of the digits of n is divisible by 3. Therefore, if n is divisible by 6, then the sum of the digits of n is divisible by 3. (b). If this function is ______________ then this function is differentiable. If this function is ______________ then this function is continuous. Therefore, if this function is a polynomial, then this function ______________. a. If all computer programs contain errors, then this program contains an error. This program does not contain an error. Therefore, it is not the case that all computer programs contain errors. b. If ______________, then ______________. Tom is not Python Programmer.
