Question

If cosec theta-sin theta=p and sec theta-cos theta=q, prove that p square ×q square (p square +q square +3)=1

Answer 1

very good very good answer for examination

Answer 2

[cosectheta-sintheta]^2+[sectheta-costheta]^2  

[1\sintheta-sintheta]   +[1\costheta-costhet]^2

[1-sintheta\sintheta]^2    +  [1-costheta\costheta]^2

    next you can solve by yourself:]
