Calculate the force F needed to punch at 1.46cm diametre hole in a steel plate 1.27cm tjick. tbe ultimate shear stress of the steel is 3.45×10^(8N/m^2 )
Given the function
f(x) = ((ln x)/(x−1))
(a) State the domain D_f of f.
(b) Find lim_(x→∞) ((ln x)/(x−1)). State its asymptotes.
(c) Draw up a variation table for the curve y = f(x).
