What is the domain of the sine and cosine functions?

Mathematics

Remember that the domain is all possible x values of a function. In the case of sine and cosine functions, they go up and down (like waves), but go on forever. Therefore, the domain is all real numbers.

Correct Answer: B, All Real Numbers

Hope this helps!

<h3>Answer: B.  All real numbers</h3>

Explanation:

For the equations y = sin(x) and y = cos(x), we can replace x with any real number we want. The output y value will be between -1 and 1, inclusive of both endpoints.

The graph for each function shows a bouncing wave stretching forever to the left and right. This visually confirms the domain.

Please help me out ‼️
Westkost [7]

Answer:

7

Step-by-step explanation:

In similar triangles, corresponding elements are proportional. Then we get,

(2x + 1)/(x-1) = 10/4

4(2x +1)       = 10(x-1)

8x + 4         = 10x - 10

8x               = 10x - 14

2x               = 14

x                 = 7

Hope it helps and if it does, please mark me brainliest...
