4.If a, a, ag.....an are in A.P. and commondifference is d then the value ofsind(coseca, coseca.y + coseca, cosecaz+ ... cosecdn-1 cosecan)will be-(1) seca1 - Secon (2) coseca1 - cosecan(3) cota1-cotan(4) tandi-tanan

(1+cotA-cosecA)(1+tanA+secA)=2

Prove the following identities,where the angles involves are acute angles for which the expressions are defined:(ix) (CosecA-SinA)(SecA-CosA)=1/(tanA+cotA)

If a_1,a_2,a_3, ,a_n are in A.P. with common difference d(w h e r ed!=0) , then the sum of series. sind (coseca_1 coseca_2+coseca_2 coseca_3 +....+ coseca_(n-1) cos e ca_n) is equal to cot a_1-cot a_n
