cot^2 alpha=1+a^2 then cosec alpha+cot^3 alpha sec alpha=

Dear Student,
Please find below the solution to the asked query:

cot2α=1+a2We know thatcosec2α=1+cot2α=1+1+a2=2+a2cosecα=2+a2=2+a212...iNowcosecα+cot3α secα=cosecα+cos3αsin3α 1cosα=cosecα+cos2αsin2α.sin α =cosecα+cot2α.cosecα=cosecα1+cot2α=cosecα.cosec2α=cosec3α=2+a232 .....Using icosecα+cot3α secα=2+a232
