Question 1196029
.
<pre>

Under the link, I see a sinusoid of the amplitude of 2 units, with the period of 6 units, 
shifted 1 unit right and with the zero vertical shift.


Its equation is

    y = f(x) = {{{2*sin((2pi/6)*(x-1))}}} = {{{2*sin((pi/3)*(x-1))}}}.


Factor "2" before the sine function makes the amplitude.


Factor (x-1) in the argument makes the shifted argument.


Factor  {{{(2pi)/6}}} = {{{pi/3}}} makes the necessary period.

Solved and explained.
