If cosecA – cotA = 3 then cosecA + cotA = ?
Given:
cosecA – cotA = 3
Formula Used:
Trigonometric identity: cosec²A - cot²A = 1
Difference of squares factorization: a² - b² = (a + b)(a - b)
Solution:
We know that ,
cosec²A - cot²A = 1.
(cosecA + cotA)(cosecA - cotA) = 1
(cosecA + cotA) × 3 = 1
cosecA + cotA =
