Helpful Hints for Computer Tools for Engineers

• #11 (chapter 4) - Just be systematic and careful.
• #14 (chapter 4) - You will need some variables to keep track of which value is the minimum and which the maximum. Think carefully on how you should initialize these variables.
• #4 (chapter 6) - This one is easy. Implement the formulas in functions.
• #11 (chapter 6) - See #10. We have studied factorial implementations in class.
• #1 (chapter 7) - No hint needed.
• #2 (chapter 7) - Ho hint needed.

Hints for assignment #4: Here some hints:

• #3 (chapter 3) - First, recall how to compare real numbers (see page 136). Second, recall the standard formula for a line... y = m*x + b where m is the slope of the line. Perpendicular lines will have reciprocal slopes of opposite sign.
• #4 (chapter 3) - First, recall how to compare real numbers (see page 136). Second, think about slopes of pairs of points.
• #9 (chapter 3) - You will probably need to use some logical variables.
• #1 (chapter 4) - Very easy... output is a table. Don't forget table labels (e.g., in the header of the table).
• #2 (chapter 4) - Understand what is needed, and what is not. Watch those unit conversions!
• #5 (chapter 4) - Think back to the Fibonacci number problem in the Mathcad assignment (assignment #1).
