Surveying--

Surveying is just a engineering application of mathematics.

In surveying the mathematical models are created in order to deal with the real life situations.

Traditionally surveying observation consist of angles and distance between the points.

Hence, the method that is used for determining the distance and elevation using instruments and geometry is:

what do the different brain waves do?

explanation:

brainwaves are produced by synchronised electrical pulses from masses of neurons communicating with each other. brainwaves are detected using sensors placed on the scalp. brainwave speed is measured in hertz (cycles per second) and they are divided into bands delineating slow, moderate, and fast waves.
