Naturally, yes.

Why would you use it twice? Using it once will provide you with the shortest distance from the line to the point.

Not that I disagree, but does co-linearity necessarily follow? IIRC two lines are co-linear iff they are parellel and share a point.

For a line of the form Ax+By+C = 0, distance d from a point p is: d = |Ax+By+C|/(A2+B2)1/2 [|...| is simply the absolute value meant to keep d>/=0]

A good way to check your graphs is this (after you've made an attempt of course!).

I recommend courses in real and complex analysis. Apart from that, take the usual physics courses that your uni/college has to offer - E&M, classical, and quantum mechanics.

I have got to say, I am thoroughly impressed by the format presented on that website. I probably won't understand most of it till I am in grad school, but I am saving that link. Thanks again for all the help.

Thank you for the quick reply. I will keep that under consideration. And you're right about the differences between cosmology and astronomy. What confused me was the description of some of the astronomy courses offered. For example, AST222: Concepts of basic physics applied to a treatment of...

Hello, I am a first year undergraduate student at University of Toronto planning to pursue cosmology as a field of study in the future. There are currently two specialist programs being offered that relate to my interests (unfortunately, I was unable to find a direct link to the programs, so...
