Finding Periods of Trig Functions - Examples Part 1

in MES Science3 years ago

In this video I go in depth into determining the period of trigonometric functions and show that it is fairly easy to do so. Finding the period of any function if it exists is important since it will make graphing it much easier because you just need to know how the graph looks at the given period and repeat it forever.
