(4*cos(4*x)-4)'The calculation above is a derivative of the function f (x)
(4*cos(4*x))'+(-4)'
(4)'*cos(4*x)+4*(cos(4*x))'+(-4)'
0*cos(4*x)+4*(cos(4*x))'+(-4)'
0*cos(4*x)+4*-sin(4*x)*(4*x)'+(-4)'
0*cos(4*x)+4*-sin(4*x)*((4)'*x+4*(x)')+(-4)'
0*cos(4*x)+4*-sin(4*x)*(0*x+4*(x)')+(-4)'
0*cos(4*x)+4*-sin(4*x)*(0*x+4*1)+(-4)'
0*cos(4*x)+4*4*(-sin(4*x))+(-4)'
0*cos(4*x)+4*-4*sin(4*x)+(-4)'
0-16*sin(4*x)
-16*sin(4*x)
