1.Normals to xy=4xy=4xy=4 at (αi,βi)(\alpha_i,\beta_i)(αi,βi) concurrent at (a,b)(a,b)(a,b). Then ∑αi∑βi∏αi=\frac{\sum\alpha_i}{\sum\beta_i}\prod\alpha_i =∑βi∑αi∏αi=a.−16b/a-16b/a−16b/ab.−16a/b-16a/b−16a/bc.4b/a4b/a4b/ad.4a/b4a/b4a/bLogin to continueOnly logged in users canattempt or see the solution.
