Step -by-step explanation
The amplitude of the function y = sin(x) is 1, because the maximum value of the sine function is 1 and the minimum value is -1. The amplitude is defined as half the difference between the maximum and minimum values of the function.
So in this case, the maximum value of the sine function is 1 and the minimum value is -1, which gives a difference of 2. Half of 2 is 1, so the amplitude of the function y = sin(x) is 1
I hope this helps.
