Sanity pass for math.

[hollasch]

• For block equations, use \frac{}{} instead of /.

• Math functions should get backslashes, as in \sin, \cos, \arccos.

• Use \sqrt{} instead of sqrt().

• Cuddle inline $ delimiters (that is, no spaces between them and the equation).

• Block equations should be indented two spaces. Separate $$ delimiters from equation with a space.

In the multiplication of a scalar with a vector, do we want to standardize to * or \cdot

My preference is \cdot

[trevordblack]

Chapter 4, InOneWeekend, there are many instances of calling dot(V0, V1) within math blocks.
I gather two things from this.

1. It might be prudent to replace the dot(V0,v1) with V0 \cdot V1
2. We should remove operators for the multiplication between a scalar and a vector. e.g.
   $p(t) = A + tB$ rather than $p(t) = A + t \cdot B$ or $p(t) = A +t * B$

I'm not married to any of the above, but we should fix the mathematical notion.

[hollasch]

I don't mind dot(V0,V1), but in general agree that I like to see V0 \cdot V1.

I also agree with your point 2 above.

We should never use * in the math markup to indicate multiplication.
