Typos in PVector tutorial

[farm402]

I found a few formatting errors in the PVector tutorial (https://processing.org/tutorials/pvector):

“SPEED: xspeed and yspeed In a more advanced sketch, we could imagine this ball and world having many more properties:”

Should be something like (with a period and line-break):

SPEED: xspeed and yspeed. In a more advanced sketch, we could imagine this ball and world having many more properties:

Moving onto multiplication, we have to think a little bit differently. When we talk about multiplying a vector what we usually mean is scaling a vector. Maybe we want a vector to be twice its size or one-third its size, etc. In this case, we are saying “Multiply a vector by 2” or “Multiply a vector by 1/3&rquo;. Note we are multiplying a vector by a scalar, a single number, not another vector.

&rquo; should be: ”

The associative rule: (nm)v = n(mv) The distributive rule, 2 scalars, 1 vector: (n + m)v = nv + mv The distributive rule, 2 vectors, 1 scalar : (u +v)n = nu + nv

Line-breaks are missing.

In the (http://processing.org/reference/PVector.html)[**PVector**] class, we therefore write our normalization function as follows:

I took a look on the tutorial and found out another broken link. This and the one you mentioned are the only two broken links in that page.

You've probably done this before when programming motion. For every frame of animation (i.e. single cycle through Processing's ([http://processing.org/reference/draw_.html)draw()]]
