# Function G2lib::pointInsideCircle

- Defined in File G2lib.hxx

## Function Documentation

inline bool G2lib::pointInsideCircle(real_type x0, real_type y0, real_type c0, real_type s0, real_type k, real_type qx, real_type qy)

  Check if point `(qx,qy)` is inside the circle passing from `(x0,y0)` with tangent direction `(c0,s0)` and curvature `k`

  Parameters

    - x0 – [in] starting x-coordinate of the circle arc

    - y0 – [in] starting y-coordinate of the circle arc

    - c0 – [in] \( \cos \theta \)

    - s0 – [in] \( \sin \theta \)

    - k – [in] Curvature of the circle

    - qx – [in] x-coordinate point to check

    - qy – [in] y-coordinate point to check

  Returns

    true if point is inside
