Question

particular sound wave can be graphed using the function y = 1 sin 2x . Find the amplitude of the function.

Answer 1

$\bf y=\stackrel{\stackrel{amplitude}{\downarrow }}{1}sin(2x)$

Answer 2

Y= 1sin(2x)

As the greatest value that the function takes is 1 and that lowest value is -1

That it is oscillates the other angle will be between -1 and 1

Thus the amplitude of the given function is 1
