**A**.

**B**is the magnitude of vector

**A**times the projection of

**B**onto

**A**.

**B**.

**A**is the magnitude of vector

**B**times the projection of

**A**onto

**B**.

Correct?

**A**.

**B**=

**B**.

**A**and this makes sense. But, say you're trying to find the components of a vector

**V**in the direction of a vector

**W**. Would it matter whether or not you wrote

**V**.

**W**or

**W**.

**V**?

EDIT: Also, does anyone know what it means (geometrically speaking) to find the components of a vector in the direction of another vector? I can give an example from a book if needed.
