Area Between Curves

💡 What can this tool do? (這工具能幫我做什麼？)

Finding the area between two curves is a core application of integration. When two curves intersect within the interval, their upper/lower relationship changes! Integrating the difference directly will cause positive and negative areas to cancel out. This tool automatically detects intersection points, splits the intervals correctly, and visualizes the results dynamically!
💡 計算兩曲線所圍成的面積是積分學的核心應用之一。當兩曲線在積分區間內相交時，其上下關係會改變。本工具會自動偵測交點並正確拆分積分區間，幫助您直觀理解「上減下」的面積法則並即時視覺化驗證！
