    Writing the value of an integral as a function of one of the integrated variables?

    Almost! This is very useful because now I can calculate the brightness factor at any distance y' by doing an integral over a certain range of y-values of the effect those y-values have on my point of interest y'. To solve the problem in the real world I could just us a computer program to...

    Writing the value of an integral as a function of one of the integrated variables?

    This is not homework. I just need help tackling this analytical problem which is apparently beyond my skills. I am modeling an imaginary physical situation. What I have here in my brain, is a photo sensor in a dark room, pointed squarely at a window, from some distance away. Actually the...

    Newton's third breakage in Goldstein's classical mechanics

    Newton's third breakage in Goldstein's "classical mechanics" I was reading Goldstein's Classical Mechanics vol.2 to brush up, and didn't get far before I got stuck. The book warns that both the weak an strong forms of the action/reaction principle can be broken when forces predicted by the...
