Graphing Trigonometric Functions(cos)
By: Austin Starling
Cosine graphs along with regular sine graphs look like waves. Having various transformations with multiple outcomes of characteristics. f(x)=cosx is the parent graph having an amplitude of 1 and all the graphs have periods of 2 pi. f(x)=2cosx and f(x)=2+cosx have amplitudes of 2 and 3 but still have the period of 2 pi.
