Question

If cosec200 -cot200 = 5 then cosec200 +cot200 = ?

Answer 1

Answer:1/5

Step-by-step explanation:

Since, cosecA+cotA = 1/(cosecA-cotA)

Answer 2

Step-by-step explanation:

COSEC200-COT200=5

WE KNEW FROM IDENTITY THAT

COSEC²Ø- COT²Ø=1

≈>COSEC²200-COT²200=1

≈>(COSEC200-COT200)(COSEC200+COT200)=1

(a²-b²=(a+b)(a-b))

$≈>COSEC200+COT200= \dfrac{1}{COSEC200 - COT200}$

≈>COSEC200+COT200=⅕

SO ANSWER IS ⅕
