____________

⏩ to prove its periodicity we will have to prove sin wt = sin w(t+T)
let sin wt = y1
and y2 = sin w(t+T) 0= sin (wt + wT) = sin ( wt + 2π) = sin wt = y1

hence y1 = y2

Answer 2

Heya mate
The answer is here

Question
Prove that sin theta or cos theta is periodic in nature.

Answer
Because cycles and oscillations and things with periodicity, are all intimately related to the circle. And sin theta and cos theta are defined based on the circle.

Or
To prove y1 = y2
Let us conclude y1= wt
y2 = sinw (t +T ) 0 =sin ( wt +wT )= sin wt = y1

So , proved
