GPS AND TRIANGULATION GPS calculation works on the principle of the receiver (example the handheld GPS receiver on car or mobile) calculating the distance of that receiver from a set of known points. 1) The receiver needs to receive a straight line signal (also called line of sight) from the known point without reflection. The best things that can do that are satellites overhead. 2) To enable that‚ the US department of defence has setup 24 low earth orbit (LEO) satellites. They are called the

I can figure out my change at the store. I am even getting through this Stats class. I just wish I knew exactly why I don’t like math. It might be because it seems like such a foreign language to me. I can remember when I started learning math. I used to sit in my class and use my chisel and rock slate to carve the numbers

are many applications of math in racing. The purpose of racing is to win and in order to do that there must be a lot of math involved. If you don’t use math and use it correctly then you will not win. Mathematics is involved in racing in two ways‚ the car setup and scoring an measurements. The car setup involves tire pressure‚ down force‚ wedge‚ aerodynamic Drag‚ camber‚ track bar and valance. The scoring system also uses math. In addition to scoring math is also used to measure
