Question

1 +cot square
(1 + cosec )
= cosec prove it
​

Answer 1

Answer:

don't know but you search in Google kabhi na khabhi toh milega

Answer 2

Step-by-step explanation:

$1+ \frac{cot^{2} Ф}{1+cosecФ} = cosec Ф$

$= 1+ \frac{cosec^{2} - 1} {cosec + 1}$

we know the Trigonometric identity:

cot²A = cosec²A-1

$= 1+ \frac{(cosec+1)(cosec-1)} {cosec+1}$

By algebraic identity:

a²-b² = (a+b)(a-b)

$= 1+cosec-1$

$= cosec$

$= RHS$

HENCE PROVED ;)
