First order of business today was Algebra. I learned about graphing inequalities. So, here’s how you do it!
- Determine whether the boundary should be solid or dashed. Good shortcut: If it’s an “or equal to” it’s solid. If not, dashed. Graph this line.
- Pick a random point not on the boundary, and test it with the inequality. If it works, congratulations! Shade that side. If it doesn’t work, congratulations! Shade the other side!
Absolute value inequalities are even simpler.
- Determine if the boundary should be solid or dashed. < means dashed, > means solid. Graph it.
- Shade whatever side of the graph contains (0,0)
That’s it. Nice, simple, clean.
And onto our next topic, Game Design. Took a quiz to make sure I knew everything I learned recently, scored well, and I did some clean up, and implemented the game win screen. It’ll tell you “GOOD JOB, PLAY AGAIN?” or “YOU SUCK, PLAY AGAIN?” basically.
Lastly, Economics. I learned about demand today. Basically, people want stuff. Because stuff is good. But money is also good. And you use money to get stuff. So how do you determine if the stuff is worth your money? Who knows, but it has been shown that people will spend more money if they’ll get more bang for their buck. A billion dollars for a chocolate bar? To hell with that! 2 dollars for 50 chocolate bars? Yes please!
To make more sense out of… whatever I just wrote above, the demand for an item increases as the cost for that object goes down, up to a limit. Basically, you buy something because it’s useful, but more of it might not be as helpful. Buying 23 frying pans might not be a good idea, unless you really need them for something important.
Like making 23 pancakes at once.
