If cosec theta + Cot theta = x , find the value of cosec theta - Cot theta |
|
Answer» By identity cosec2a - cot2a =1Using identity a2-b2=[a+b][a-b] we have(Coseca+cota) (coseca- cota)=1 (by identiy at top)= x(coseca- cota)= 1( given =x)(coseca-cota)= 1/x ANSWER!! Cosec²Q-Cot²Q= 1...(CosecQ-CotQ) x (Cosec+CotQ) = 1....(CosecQ-CotQ) X (x) = 1.....CosecQ-CotQ = 1/x.. |
