Show that if u+v and u-v are orthognal, then the vectors u and v must have the same length.

Answer with Step-by-step explanation:

We are given that

u+ v and u-v are orthogonal

We have to prove that u and v must have the same length.

When two vector a and b are orthogonal then

By using the property

We know that

Magnitude is always positive

When power of base on both sides are equal then base will be equal

Therefore,

Hence, the length of vectors u and v must have the same length.
