(0.2*sin(2*40*pi*x))'The calculation above is a derivative of the function f (x)
(0.2)'*sin(2*40*pi*x)+0.2*(sin(2*40*pi*x))'
0*sin(2*40*pi*x)+0.2*(sin(2*40*pi*x))'
0*sin(2*40*pi*x)+0.2*cos(2*40*pi*x)*(2*40*pi*x)'
0*sin(2*40*pi*x)+0.2*cos(2*40*pi*x)*((2*40*pi)'*x+2*40*pi*(x)')
0*sin(2*40*pi*x)+0.2*cos(2*40*pi*x)*(0*x+2*40*pi*(x)')
0*sin(2*40*pi*x)+0.2*cos(2*40*pi*x)*(0*x+2*40*pi*1)
0*sin(2*40*pi*x)+0.2*80*pi*cos(2*40*pi*x)
0*sin(2*40*pi*x)+0.2*80*pi*cos(80*pi*x)
16*pi*cos(80*pi*x)
