Question

solve it only if you know. ​

Answer 1

Given sinA - 1 = 1 - cosecA

=> sin A + Cosec A = 1 + 1

=> sin A + Cosec A = 2

/* On squaring both sides of the equation, we get*/

=> (SinA + cosecA )²= 2²

=> Sin²A + Cosec² A + 2sinAcosecA = 4

=> Sin²A + Cosec² A + 2= 4

__________________

Since , SinA cosecA = 1

____________________

=> Sin²A + Cosec² A = 4 - 2

=> Sin²A + Cosec² A = 2

Therefore,.

$\red{ Value \:of \: sin^{2} A+ Cosec^{2} A } \green {= 2}$
