Question

Cosec thita (sec thita-1)-cot thita(1-cos thita)=tan thita-sin thita

Answer 1

Step-by-step explanation:

Please see below. Explanation: sinθ1−cosθ+tanθ1+cosθ. = sinθ(1+cosθ)(1−cosθ)(1+cosθ)+tanθ(1−cosθ)(1+cosθ)(1−cosθ).

Please see below. Explanation: sinθ1−cosθ+tanθ1+cosθ = sinθ(1+cosθ)(1−cosθ)(1+cosθ)+tanθ(1−cosθ)(1+cosθ)(1−cosθ) = sinθ(1+cosθ)1−cos ... More
