Using Taylor's Series expansions, derive a third-order forward finite difference approximation of the first derivative f' at point xi. Hint: use points xi, xi+1, xi+2, and xi+3.
The Sharp-razor Company manufactures two types of electric shavers. One shaver is cordless and It requires 5 hours to manufacture. The other shaver has an electric cord and it takes 3 hours to manufacture it. The company has only 16 work hours per day to manufacture shavers. The despatch department can pack and ship at most 300 shavers per day. Let $z$ be the number of cordless shavers made per day and $y$ be the number of shavers with a cord manufactured per day. The correct system of linear inequalities that represents this situation is a. $5x + 3y \le 16$; $x + y \le 3$ b. $5x + 3y \le 300$; $x + y \le 3$ c. $5x + 3y \le 16$; $x + y \ge 3$ d. $5x + 3y \ge 16$; $x + y \ge 3$
