Question

If sinA+cosecA=2 then find sin²A+cosec²A​

Answer 1

Step-by-step explanation:

follow the above steps

Answer 2

Answer:

sin A + cosec A =2

or,sinA +1/sinA=2

or,sin^2A+1=2sinA

or,sin^2A-2sinA+1=0

or,( sin^2A-1)^2=0

or, sin^2A-1=0

or,sinA=1

or,cosecA=1

or,

sin^2A+cosec^2A=1+1=2..........
