Document Summary

Understand direct and inverse proportional relationships between variables. Direct relationship: if x increases then y increases. Indirect relationship: if x increases then y decreases. Related or proportional: two items are associated or affiliated. How to convert a decimal number to binary and vice versa. Bit: the smallest amount of computer memory. Byte: a group of eight bits of computer memory. Divide number by 2 and ignore remainder, odd is 1 and even is 0. Binary to decimal--- right to left start with 2^0 and then add 2^0= 1. Memorize distance equation (distance = rate x time) Distance= round trip, imaging depth= deep in patients body. Basic understanding of trigonometry (cosine 0 degrees = 1, cosine 60 degrees = 0. 5, cosine 90 degrees = 0. Definition of a wave, mechanical vs electromagnetic, longitudinal vs. Waves are a cyclical transfer of energy. Sound is a mechanical wave: needs a medium. Electromagnetic wave: will work in medium or vacuum.
