Answer:

 \\ (\csc(Q)  -  \cot(Q)) \:  =  \frac{1}{x}  \\

Step-by-step explanation:

Given :

cosecQ + cotQ = x

To Find : cosecQ - cotQ

Solution:

 \\  \\  \csc(Q)   +  \cot(Q)  = x \\  \\ but \:  \: we \:  \: know \: that \:  \\  \\  \\   { (\csc(Q)) }^{2}  -  { (\cot(Q)) }^{2}  = 1 \\  \\  \\ but \:  {a}^{2}  -  {b}^{2}  = (a + b)(a - b) \\  \\

So, we get;

 \\ ( \csc(Q)  +   \cot(Q)  )( \csc(Q)  -  \cot(Q) ) = 1 \\  \\ putting \:  \: given \: value \:  \\  \\  \\ x \:  \times (\csc(Q)  -  \cot(Q)) = 1 \\  \\ so \:  \: (\csc(Q)  -  \cot(Q)) \:  =  \:  \frac{1}{x}  \\  \\

Thanks.
