What Is the Difference Between an Orthogonal Complement and Its Basis?

Click For Summary
The discussion revolves around the confusion between an orthogonal complement and its basis in linear algebra. The user is working on a problem involving the orthogonal complement of the subspace defined by the equation 2x - y + 3z = 0 and has attempted to find it using reduced row echelon form. They have derived vectors from the nullspace, questioning whether these represent the orthogonal complement or its basis. The user also requests the deletion of their original thread to avoid discouraging responses. Clarifying the distinction between the two concepts is essential for understanding their application in linear algebra.

Homework Statement


I don't understand the difference between an orthogonal complement and it's basis. In this problem: W = [x,y,z]: 2x-y+3z=0 Find w's orthogonal complement and the basis for the orthogonal complement.

The Attempt at a Solution


I did a quick reduced row echelon to [2,-1,3] to get [1,-.5,1.5] and then found the nullspace which is [.5,1,0] and [-1.5,0,1] and this is either the orthogonal complement or the orthogonal complement's basis. Anyone know the difference?

I essentially answered my question before. My first one was getting convoluted with my posts. So I started a new one based on a different question. Would you mind deleting my original thread? And if you do, would you mind deleting your post claiming I started multiple threads so as not to discourage people from helping.

Thanks
 
Question: A clock's minute hand has length 4 and its hour hand has length 3. What is the distance between the tips at the moment when it is increasing most rapidly?(Putnam Exam Question) Answer: Making assumption that both the hands moves at constant angular velocities, the answer is ## \sqrt{7} .## But don't you think this assumption is somewhat doubtful and wrong?
