    Tips for Advancing in Math, Physics, and Chemistry Without an Associates Degree

    I took a couple of masters courses during my undergrad, albeit not as a freshman. I found they were a very stimulating supplement to the introductory-level classes, and I was able to perform well on the coursework too. None of my peers thought I was an elitist for doing so (they all knew how big...

    Undergrad Classification of Three-Dimensional Forces/Vectors

    Searching Category:Force on wikipedia will yield an extensive list. Like dipole said the only canonical classification of forces is the four fundamental interactions. Common engineering terminology includes: compression and tension forces in statics; centripetal, centrifugal, and Coriolis...

    Undergrad Coordinates of a point outside a plane

    If you are given: A=(A_1,A_2,A_3) B=(B_1,B_2,B_3) C=(C_1,C_2,C_3) And you want to find G=(G_1,G_2,G_3), then knowing: 1) AG=|A-G|=((A_1-G_1)^2+(A_2-G_2)^2+(A_3-G_3)^2)^(1/2) 2) BG=|B-G| 3) CG=|C-G| is not enough information. Let h be the perpendicular distance from G to the plane. Then if...
