1−1−cosA

1−cosA1+cosA =

= (1−cosA)(1+cosA)

= (1−cosA)(1+cosA)(1+cosA) 2 =

= sin2A

= sin2A(1+cosA) =

= (cosecA+cotA) 2

2 =∣cosecA+cotA∣

2 =∣cosecA+cotA∣=cosecA+cotA (as given)

2 =∣cosecA+cotA∣=cosecA+cotA (as given)let cosecA + cotA = x

2 =∣cosecA+cotA∣=cosecA+cotA (as given)let cosecA + cotA = xso we get |x| = x

2 =∣cosecA+cotA∣=cosecA+cotA (as given)let cosecA + cotA = xso we get |x| = xthis is possible only when x ⩾ 0

2 =∣cosecA+cotA∣=cosecA+cotA (as given)let cosecA + cotA = xso we get |x| = xthis is possible only when x ⩾ 0so cosecA + cotA ⩾ 0

2 =∣cosecA+cotA∣=cosecA+cotA (as given)let cosecA + cotA = xso we get |x| = xthis is possible only when x ⩾ 0so cosecA + cotA ⩾ 0this means that sinA > 0

2 =∣cosecA+cotA∣=cosecA+cotA (as given)let cosecA + cotA = xso we get |x| = xthis is possible only when x ⩾ 0so cosecA + cotA ⩾ 0this means that sinA > 0this is possible only in first and second quadrants

Answer 2

Step-by-step explanation:

1−1−cosA

1−cosA1+cosA =

= (1−cosA)(1+cosA)

= (1−cosA)(1+cosA)(1+cosA) 2 =

= sin2A

= sin2A(1+cosA) =

= (cosecA+cotA) 2

2 =∣cosecA+cotA∣

2 =∣cosecA+cotA∣=cosecA+cotA (as given)

2 =∣cosecA+cotA∣=cosecA+cotA (as given)let cosecA + cotA = x

2 =∣cosecA+cotA∣=cosecA+cotA (as given)let cosecA + cotA = xso we get |x| = x

2 =∣cosecA+cotA∣=cosecA+cotA (as given)let cosecA + cotA = xso we get |x| = xthis is possible only when x ⩾ 0

2 =∣cosecA+cotA∣=cosecA+cotA (as given)let cosecA + cotA = xso we get |x| = xthis is possible only when x ⩾ 0so cosecA + cotA ⩾ 0

2 =∣cosecA+cotA∣=cosecA+cotA (as given)let cosecA + cotA = xso we get |x| = xthis is possible only when x ⩾ 0so cosecA + cotA ⩾ 0this means that sinA > 0
