Hey !!!
cos( π + x ) cos ( - x)
--------------------------------
sin ( π - x ) cos ( π/2 + x)
See triagomometric table
we will get
cos( π + x ) = - cosx
cos (-x) = cosx
sin( π - x ) = sinx
cos ( π/2 + x ) = - sinx
using these terminology
=> (- cosx )× cosx / sinx × (- sinx )
=> - cos²x /- sin²x
=> cos²x/sin²x
=> cot²x Rhs prooved ♻
