Hi, I have no knowledge of Calculus. I am actually studying Computer Science. One of the exercises in the textbook I am using ("Python Programming" by John Zelle) suggests that the answer to the problem can be solved either through a simple simulation program or through calculus. I am still struggling with this, but even if I do find a solution, t I have no way of checking my answer, so I was wondering what solutions using calculus might bring. The problem (Chapter 9, Exercise 15) is as follows: You are at the exact center of a cube. You can see all six faces of the cube equally, so you can say that each face of the cube occupies 1/6 of your vision. Say you move exactly half of the distance from the center of the cube to the center point of one of its faces. What fraction (or percentage) of your vision does the closest face now occupy? I would love to know what solution using calculus produces - it would give me a point of reference from which to work through the simulation. I am having trouble even doing this as a "simple" simulation, because my linear algebra is not up to snuff. Granted it's important for me to get it up to snuff, I am not studying it right now, and this book did not say that knowing it was a requirement. Thanks, everyone.
