(1-tan α) / (1 + Tan α) = 3-2 √ 2 find the value of [(sin α + cos α) ^ 2-1] / (cot α - sin α times cos α)

[(sin α + cos α) ^ 2-1] / (cot α - sin α multiplied by cos α) = 2sinacosa / (COTA sinacoa) = 2 / [(CSCA) ^ 2-1] = 2 (Tana) ^ 2 is derived from (1-tan α) / (1 + Tan α) = 3-2 √ 21 Tana = (3-2 √ 2) + (3-2 √ 2) Tana, that is, (2 √ 2-4) Tana = 2-2 √ 2tana = (2-2 √ 2) / (2 √ 2-4)
