(5.1*ln(6.2*x-12))'The calculation above is a derivative of the function f (x)
(5.1)'*ln(6.2*x-12)+5.1*(ln(6.2*x-12))'
0*ln(6.2*x-12)+5.1*(ln(6.2*x-12))'
0*ln(6.2*x-12)+5.1*(1/(6.2*x-12))*(6.2*x-12)'
0*ln(6.2*x-12)+5.1*(1/(6.2*x-12))*((6.2*x)'+(-12)')
0*ln(6.2*x-12)+5.1*(1/(6.2*x-12))*(6.2*(x)'+(6.2)'*x+(-12)')
0*ln(6.2*x-12)+5.1*(1/(6.2*x-12))*(6.2*(x)'+0*x+(-12)')
0*ln(6.2*x-12)+5.1*(1/(6.2*x-12))*(0*x+6.2*1+(-12)')
0*ln(6.2*x-12)+5.1*(0+6.2)*(1/(6.2*x-12))
0*ln(6.2*x-12)+5.1*(6.2/(6.2*x-12))
