ines will be possible. Consequently, therewill be no solution. This will happen when the line A is parallel, ornearly so, to the axis of the cone. A special case, in which one, and only one, solution exists, will occurwhen the line B, parallel to A, is found to coincide with an element ofthe given… … which passes through the given point, and a line tangent to thebase at the point where this element intersects the base. Construction. Case I. The base of the cylinder lies in H or V(Tig. 282). The construction is entirely similar to that for thecorresponding case of the cone (Prob. 31, Case I),…
