## Are the domain and range for the sine and cosine functions are the same?

Domain and range for sine and cosine functions There are no restrictions on the domain of sine and cosine functions; therefore, their domain is such that x ∈ R. Notice, however, that the range for both y = sin(x) and y = cos(x) is between -1 and 1.

## Why is the domain of sin and cos all real numbers?

We can calculate the domain and range of cos(x). As we saw in the case of sin(x), for any point on a unit circle, the cos(x) is equal to adjacent / 1. The measure of adjacent can be defined for all the points on the circle, indicating that the angle x can take any value. So, the domain of cos(x) is all real numbers.

## Are sine and cosine functions the same?

Sine and cosine — a.k.a., sin(θ) and cos(θ) — are functions revealing the shape of a right triangle. Looking out from a vertex with angle θ, sin(θ) is the ratio of the opposite side to the hypotenuse , while cos(θ) is the ratio of the adjacent side to the hypotenuse .

## Are sin and cos graphs the same?

The graph of sine has the same shape as the graph of cosine. Indeed, the graph of sine can be obtained by translating the graph of cosine by ( 4 n + 1 ) π 2 \frac{(4n+1)\pi}{2} 2(4n+1)π units along the positive x x x-axis ( n n n is an integer).
