Question

please give me answer of maths question 3​

Answer 1

Answer:

hello friend here is your ans

Step-by-step explanation:

L.H.S. =(sinA+cosecA) 2 +(cosA+secA) 2

=sin 2A+cosec 2 A+2sinAcosecA+cos 2 A+sec 2 A+2cosAsecA

=1+2+2+1+tan 2 A+1+cot 2 A

=7+tan 2 A+cot 2 A = R.H.S.

Answer 2

Step-by-step explanation:

sin^2(A) +cos^2(A)=1

cosec^2(A)= 1+cot^2(A)

sec^2(A)= 1+ tan^2(A/

sin(A)×cosec(A)=1

cos(A)×cot(A)=1
