Class Summaries 4/30

Precalc

More discussion of vector problems. Test is coming up next Tuesday...early turn in for the applications problems is tomorrow. Homework is on the back of the examples, but different depending on what period you are in.

Also, if you're curious, here is the wikipedia article on the normal force. I'll make sure and draw it this way from now on to be consistent with physics (even though the math is the same regardless of how it's drawn).
  • Examples from today
  • First period should do 1, 2, and the first two problems labelled "Resultant Force".
  • Second period should do 1, 2, the second Resultant Force problem, and #67.

Tic Tac Toe game to review Chapter 6. Test is tomorrow!

Computer Science 2

Work on exercise 2. If you manage to finish early, here's a bonus opportunity that I will also make due Monday at 2:30pm (due to the nature of this assignment being a bonus, it will be much more open ended than the other assignments):

Design a RolePlayingCharacter class. The RolePlayingCharacter class should have variables that control the amount of damage the character does, the amount of armor(defense) the character has, how much health they have, and any other relevant info about the character. It should also have "get" methods for displaying their health, and other needed info.

To test your class, I've created a main method that instantiates an object of type RolePlayingClass, and uses methods that I feel you should have. You may modify my main in any way that you'd like.

To get credit, you simply need to show me your code in class and run the main that I provide for you to verify that it works.

Wrap up of all open assignments.  Book exercises due today at 2:30pm.  

In addition, do the following two programs, due Monday at 2:30pm:

1.  Write a program that adds up the first n odd integers, where n is a number specified by the user, using a for loop.  (For example - if the user enters in 9, the program should compute 1 + 3 + 5 + 7 + 9).  Repeat until the user wants to stop (you can do this part with any loop you'd like).  (Side note - do you notice a connection between the number that is entered and the answer?)

2.  Recall the program that you wrote that searches a sentence for a particular char.  Rewrite this program so that it utilizes a for loop.
