Finding Reflection of a Vector

Click For Summary
SUMMARY

The reflection of the vector v = i - 3j + 2k around the line defined by W = i - k can be calculated using vector projection. First, compute the vector projection of v onto W, denoted as Vp. The reflected vector v' is then obtained using the formula v' = 2Vp - v. This method effectively utilizes geometric principles to visualize the reflection process.

Find the reflection v' of v=i-3j+2k around the line i-k

how can I do that? I am extremely rusty with math these days;
 
Physics news on Phys.org
Call i-k = W. I would calculate the vector projection of V on W, call it Vp. Then the reflected vector is 2Vp-V. Draw a little triangle/parallelogram and you will see it.
