yi 4:a Since abscissa of P= abscissa of :Z^ + abscissa of V there- fore, by Art. 22, Cor., Pmiddle point of TV. Also the tangent at P is 2/1 is the … yy,= 2a^.^f^ which is parallel to (1). Hence the polar of T is parallelto the tangent at P. To draw the polar of T we therefore draw a line throughT, parallel to the axis, to meet the curve in P and produceit to Fso that TP-PV; a line through F parallel to thetangent at P is then the polar…
