Question

QL LL o 7
Cosec 0 = 7 Then, evaluate
cot o - Cosec o​

Answer 1

Step-by-step explanation:

Cosec 0 = 7 = H/P

it means

H = 7

P = 1

B= ?

H^2 = P^2+B^2

7^2 = 1^2+B^2

49 = 1 + B^2

B^2 = 49-1

B^2 = 48

B^2 = 4√3

cot o = B/P = 4√3/1

codec o = H/P = 7/1

cot o - Cosec o

cot o - Cosec o 4√3 - 7
