ratio and proportions
Try to get all variables (letters) on one side, numbers on the other. Your problem is that the answer, w, is divided by 5 on the lhs. You must do the opposite (ie multiply by 5) throughout the
expression (do it on both sides) to remove the offending 5 and hence get w = ....

I do not understand what is the difference between the line that is drawn by glBegin(GL_LINE) and the line which is drawn by DDA algorithm.
and I do not know whether DDA is better than glBegin(GL_LINE) or not.

Misadventures with bitwise operators
I'm trying to make a program that solves exercise 2-6 in K&R: "Write a function setbits(x,p,n,y) that returns x with the n bits that begin at position p set to the rightmost n bits of y, leaving
the other bits unchanged."
