=1+2+2+(cosec^2A+sec^2A)
=5+((sin^2A+cos^2A)/(cos^2A.sin^2A))
=5+(sec^2A.cosec^2A)
=5+(1+tan^2A)(1+cot^2A)
=5+1+cot^2A+tan^2A+tan^2A.cot^2A
=5+1+1+cot^2A+tan^2A
=7+tan^2A+cot^2A

ok
+(2.co complete this plz i cant understand it
oh
=sin^2A +2sinAcscA +csc^2A +cos^2A +2cosAsecA +sec^2A
=sin^2A +cos^2A +2(1) +2(1) +csc^2A +sec^2A
=5 +(1 +cot^2A) + (tan^2A+1)
=7 +tan^2A +cot^2A
=sin^2A +cos^2A +2(1) +2(1) +csc^2A +sec^2A
=5 +(1 +cot^2A) + (tan^2A+1)
=7 +tan^2A +cot^2A
this is the second answer
thank u very much
where there are = there the next line starts ok
wlcm
kkk
hmm
