What is the Value of sin and cos infinity?
Answer: The value of sin and cos infinity lies between -1 to 1. There are no exact values defined for them.
Let's understand the conclusion.
We know that,
(-1) ≤ sin x, cos x ≤ (+1) for x ε (-α, +α)
i.e., The value of sin x and cos x always lies in the range of -1 to 1.
Also, ∞ is undefined thus, sin(∞) and cos(∞) cannot have exact defined values.
However, sin x and cos x are periodic functions having a periodicity of (2π).
