Let Q: x2 > x + 1 where x is a positive integer. Assume that Q is true after the kth iteration of the following while loop; prove that Q is true after the next iteration. while (x > 5) and (x < 40) do x = x + 1 end while

Ch. 14.9 Parameterized Surfaces 1. Parameterization is usually done when one of the variables can be represented as either a constant or a function of the other two variables. In these cases, the constant or function is substituted for the third variable yielding a function of two variables. 2. For a surface parameterized by the...
