Can you someone please help me with this question??? Simplify cot(x + pi)

  • Pre-Calc -

    you could do this ...

    cot(x + pi)
    = cos(x+π)/sin(x+π)
    = -cosx/-sinx
    = cotx

    or

    cot(x+π) = 1/tan(x+π) ,
    = 1/tanx , since x+π is in quadrant III and according to CAST, in III the tangent is positive.
    = cotx
