(12*ln(7*x)-4)'The calculation above is a derivative of the function f (x)
(12*ln(7*x))'+(-4)'
(12)'*ln(7*x)+12*(ln(7*x))'+(-4)'
0*ln(7*x)+12*(ln(7*x))'+(-4)'
0*ln(7*x)+12*(1/(7*x))*(7*x)'+(-4)'
0*ln(7*x)+12*(1/(7*x))*((7)'*x+7*(x)')+(-4)'
0*ln(7*x)+12*(1/(7*x))*(0*x+7*(x)')+(-4)'
0*ln(7*x)+12*(1/(7*x))*(0*x+7*1)+(-4)'
0*ln(7*x)+12*x^-1+(-4)'
12*x^-1+0
12*x^-1
