Sin theta ×sin theta /cosec theta |
|
Answer» Sin×Sin=sin square= 1-cos square/cosec. Cosec=1/sin hence sin(1-cos square) apply identity a2-b2 Sin(1+cos)(1-cos) I think answer is cosec theta as Sin=1/cosec and vice versa ATQ Sin theta × sin/cosec=> Sin theta × cosec theta / sin theta=> Sin theta wil be cancelled=> Cosec thetaHence the answer is cosec theta |
