Help, the original question is like this: Sin (540-x) / Tan (900-x) multiplied by 1 / Tan (450-x) Tan (810-x) multiplied by cos (360-x) / sin (- x) If TaNx = 2 How can I simplify it? It's really evil,

Help, the original question is like this: Sin (540-x) / Tan (900-x) multiplied by 1 / Tan (450-x) Tan (810-x) multiplied by cos (360-x) / sin (- x) If TaNx = 2 How can I simplify it? It's really evil,

The original formula is: sin (540-x) / Tan (900-x) * 1 / (Tan (450-x) Tan (810-x)) * cos (360-x) / sin (- x) sin (540-x) = sin (180-x) = sinxtan (900-x) = Tan (- x) = Tan (450-x) = Tan (90-x) = cotxtan (810-x) = Tan (90-x) = cotxcos (360-x) = cos (- x) =
