Answer 1

Answer:

Thi is helpful u

Step-by-step explanation:

The sin function is one taught in trigonometry. It takes in one real valued input, and gives one real valued output. This can be graphed in 2D. The graph looks wave-like, repeating a pattern in period. This input gives one point of output. Underneath this is the algebraic expansion, which is an infinite sum. This follows some defined pattern.
