Lead is not as conductive as aluminum. The methods are: 1. Let I=f(z)/f(z)dzI=\oint f^{\prime}(z) / f(z) d zI=f(z)/f(z)dz about infinity, that is, in the negative direction around a very large circle C. Use the argument principle and also evaluate I by finding the residue of f(z)/f(z)f^{\prime}(z) / f(z)f(z)/f(z) at infinity; thus show that f(z) has n zeros inside C. T/F: One possible indicator that a barrel is likely to shoot poorly is pitting near the crown.
