No period

ok thanks

woh yeh hai ki :

ek ka period hai hi nahi.

aur ek ka hai, par tum bata nahi paoge ki woh kya hai..

think about the graph for any constant f(x)=k.

a straight line parallel to x-axis.

it is periodic at each single real point on the no. line.

In mathematics, a periodic function is a function that repeats its values in regular intervals or periods. The most important examples are the trigonometric functions, which repeat over intervals of length 2Ï€. Periodic functions are used throughout science to describe oscillations, waves, and other phenomena that exhibit periodicity.

If a function f is periodic with period P, then for all x in the domain of f and all integers n,

f(x + nP) = f(x).
