Question

(COSA + 1 - SinA) /
(COSA - 1 + SinA) is equal to
CosecA + CotA​

Answer 1

cosA−sinA+1cosA+sinA−1cos⁡A−sin⁡A+1cos⁡A+sin⁡A−1

=(cosA−sinA+1)(cosA+sinA+1)(cosA+sinA−1)(cosA+sinA+1)=(cos⁡A−sin⁡A+1)(cos⁡A+sin⁡A+1)(cos⁡A+sin⁡A−1)(cos⁡A+sin⁡A+1)

=(cosA+1¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯−sinA)(cosA+1¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯+sinA)(cosA+sinA¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯−1)(cos
