Question

the derivatives of narrate

Answer 1

Our next task is to determine what is the derivative of the natural logarithm.  We begin with the inverse definition.  If          y  =  ln x  then          ey  =  x  Now implicitly take the derivative of both sides with respect to x remembering to multiply by dy/dx on the left hand side since it is given in terms of y not x.          ey dy/dx  =  1
