如何计算Cross Product3 D
learn.whatIsHeading
3D cross product of two vectors produces third perpendicular vector, used for normal calculations, torque, angular momentum.
分步指南
- 1Input two 3D vectors (x,y,z)
- 2Calculate a × b using determinant method
- 3Result shows magnitude and direction
例题解析
输入
a=(1,0,0), b=(0,1,0)
结果
a×b = (0,0,1) (perpendicular to both)
常见错误注意事项
- ✕Forgetting right-hand rule
- ✕Confusing with dot product
常见问题
Does order matter?
Yes, a×b = -b×a (anticommutative).
