Question

sinA+cosecA=2 then sin²A+cosec²A=???? answer it with u r brain​

Answer 1

Answer:

2

Step-by-step explanation:

sinA+cosecA=2

Squaring both sides-:

sin²A+cosec²A +2sinAcosecA = 4

sin²A+cosec²A = 4-2

sin²A+cosec²A = 2

Answer 2

sinA + cosecA = 2

square both side

(sinA + cosecA)² = 2²

sin²A + cosec²A + 2 × sin A × cosec A = 4

sin²A + cosec²A + 2 × sin A × 1/sin A = 4 .....( cosec A = 1/ sin A)

sin²A + cosec²A = 4-2 = 2
