Answer:
maximum value that the graph y = cos x assumes is 1
Explanation:
y =cos x is the function given.
By definition of trignometric ratios, cos x = adjacent side/hypotenuse of a right triangle.
Obviously hypotenuse can never be less than a side and hence cos x can take maximum value as 1 only
cosx is a periodic function with period 2pi and maximum value 1
maximum value that the graph of y = cos x assumes=1
