Hello i think this should be easy but I'm stuck in it (function graphing)

Hello, can you help me with this graphing question please?? i keep getting errors

-this is the mathematical question:-

 in the same window, for x between x=0 and x= 2*pi, plot the two functions when a = 16

1- y=sin x

2- y = sin ( x - 4*pi/a)

-this is my attempt :-

a=16; fplot('sin(x)',[0,2*pi]) %the first graph appeared

hold on

fplot('sin(x-4*pi/a)',[0,2*pi])

   Error using inline/feval (line 22)
Not enough inputs to inline function.

Error in fplot (line 101) x = xmin; y = feval(fun,x,args{4:end});

It’s not picking up ‘a’ from your workspace. An anonymous function will:

a=16;
fplot(@(x) sin(x), [0,2*pi])  %the first graph appeared 
hold on
fplot(@(x) sin(x-4*pi/a), [0,2*pi])
