If cosec A -cot A= 3/2 , find cos A and also the quadrant in which A lies.

If cosec theta+cot theta =k" then "cos theta =………….

If cosec x-cot x=(1)/(3), where x!=0, then the value of cos^(2)x-sin^(2)x is

cosec A- 2cot 2A cos A=

( cos A - sin A + 1 ) / ( cos A + sin A - 1 ) = cosec A + cot A cosec A + cot A , = using the identity cosec ^ 2 A = 1 + cot^ 2 A .

Prove that cosec A -2 cot 2 A cos A = 2 sin A.

If cosec theta+cot theta=-(3)/(2) then find cosec theta
