Vector Addition and Subtraction Demonstration by goh see khai eric

This example demonstrates the addition and subtraction of vectors in a two-dimensional plane and their geometric interpretations. The core mathematical concepts involved include vectors, their geometric representation, the parallelogram and triangle laws for vector addition, and the definition of vector subtraction. The construction utilizes GeoGebra commands and objects such as Textfield, Vector; objects: k1, k2, x1, x2, y1, y2, inputBox1, inputBox2, inputBox3, inputBox4, inputBox5, inputBox6, text1, text2, button1, U1, U2, U3, U4, u, v, w, a, b, text3, text4, text5, text6, U5, U6, c, d, e, f, text7, button2, text8, text9, button3. This example is suitable for high school students learning basic vector operations, helping them deepen their understanding of the geometric meanings of vector addition and subtraction through interactive manipulation, and can be used as an auxiliary tool for classroom teaching or after-school exercises.
