If sin θ + cosec θ = 2, then sin2θ + cosec2θ is equal to (a) 1(b) 4(c) 2(d) none of these

If sin θ + cosec θ = 2, then sin2θ + cosec2θ is equal to (a) 1(b)

1.	If sin θ + cosec θ = 2, then sin2θ + cosec2θ is equal to (a) 1(b) 4(c) 2(d) none of these
Answer» If sin θ + cosec θ = 2, then sin²θ + cosec²θ is equal to (a) 1 (b) 4 (c) 2 (d) none of these
