Question

if cosec theta + cot theta = 7/3 find sin theta - cosec theta.
No useless answer or get reported.​

Answer 1

Step-by-step explanation:

if cosec∅+cos∅=x then

cosec∅ - cos∅= 1/x

now,

cosec∅ + cos∅= 7/3 eq.1

cosec∅ - cos∅= 3/7 eq.2

on adding both eq. We get,

2cosec∅= 58/21

cosec∅= 29/21

cosec∅=29/21

1/sin∅= 29/21

sin∅= 21/29

sin∅ - cosec∅

21/29 - 29/21

(441-841)/29×21

-(400/609)
