The SI unit of frequency is Hz. This is inversely proportional to wavelength, and is a measure of the number of oscillations of a waveform per second. It is also used to describe the rate at which a current changes direction. It is an important unit to know if you want to make the most accurate measurements.
Hz is the...
The Law of Cosines is a fundamental mathematical principle, and it can be used to calculate central angles. If two points are located on a circle, their central angle will be -1. Similarly, if two arcs are congruent, they will have congruent central angles.
Theorem of the law of cosines
The law of cosines is a mathematical tool that is used...
The basic way to tell time on an analog clock is to know which hands are on which hour. The three hands are the Hour hand, Second hand and Minute hand. The minute hand points at seven. Counting by fives is another way to read a clock. Here are some examples.
Three hands
A three-hand analog clock is an old-fashioned clock...
