如何计算Vector Addition
learn.whatIsHeading
Vector addition combines vectors head-to-tail; results in resultant vector (parallelogram method or component-wise).
分步指南
- 1Input two vectors (component form)
- 2Add components: (a₁+b₁, a₂+b₂, a₃+b₃)
- 3Results show sum vector and magnitude
例题解析
输入
a=(3,4), b=(1,2)
结果
a+b=(4,6), |a+b|=√52≈7.21
常见错误注意事项
- ✕Adding magnitudes instead of components
- ✕Confusing with scalar multiplication
常见问题
Is vector addition commutative?
Yes, a+b = b+a (unlike subtraction).
