3-2. Extension to \(-π〜π\)

Extension to \(-π〜π\) is enabled by converting theta input to the CORDIC circuit. Specifically, it is possible to calculate by using a conventional sin and cos by a \(π-θ\) when the input theta has exceeded a -\(π\)/2〜\(π\)/2. However, it is necessary to pay attention to the possibility that the sign is inverted.

Thus in order to be easy with respect to extension, as a subject of this LSI design contest are targeted at -\(π\)/2〜\(π\)/2
