What are some periodic functions?

Answer 1

f(x) = sin(x)

f(x) = cos(x)

f(x) = tan(x)

f(x) = sin(2x)

f(x) = cos(2x)

f(x) = tan(2x)

Answer 2

Some examples of periodic functions include sine and cosine functions, square wave functions, and sawtooth wave functions. These functions repeat themselves over a given interval, called the period, and have the same values at regular intervals.
