BQ #2 unit T

What is a period ?
A period is a set of repeating graphs

Why is the period for sin and cosine 2 pie ?
It is because when graphing it the quadrants are different in sin and cosine have the negative on the same side as the other negatives and some with positives. it needs to go threw one whole round of it for a graph to finish.

What is amplitude ?
it is what number that will determine how far your graph will go up.

Why does sin and cosine have amplitudes of 1?
as you see in the unite circle we see that sin and cosine both have the hypotenuse in its equation and on the unit circle that hypotenuse is always one no matter what.
