Question

how to find value of '' y '' in Cos

Answer 1

Step-by-step explanation:

The fact that the cosine function repeats itself means that that it is periodic. In particular, y = cos x is periodic with period 2π . This means that if the point (x, y) lies on the graph, then the point (x+2kπ, y) will also lie on the graph where k is any integer.

Answer 2

Answer:

Properties of the Cosine Function, y=cos(x) .

x -intercept : (nπ2,0) , where n is an integer. The maximum value of y=cos(x) occurs when x=2nπ , where n is an integer. The minimum value of y=cos(x) occurs when x=π+2nπ , where n is an integer.
