# What is the Value of sin and cos infinity?

**Solution:**

Trigonometry helps us to understand the relation between the sides and angles of a triangle. Sin and Cos are two of the six trigonometric ratios of a right-angled triangle.

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).

Thus, the value of sin and cos infinity lies between -1 to 1. There are no exact values defined for them.

## What is the Value of sin and cos infinity?

**Summary:**

The value of sin and cos infinity lies between -1 to 1. There are no exact values defined for them.
