What is the sequence 50 -50 50 -50?
Alternating adding and subtracting 100
What does frequency mean in relation to alternating current?
Alternating current (AC) continually flows in one direction then it changes direction and flows the other way. This switching back and forth creates what is called a sinusoid or sine wave. Frequency is the rate of this back and forth switching in alternating current. Frequency is measured in Hertz (Hz) which is the number times a wave switches back and forth PER SECOND or better described as CYCLES PER SECOND.
Is the relation a function?
Not every relation is a function. But every function is a relation. Function is just a part of relation.
