Let and solve the simultaneous linear equations . You should then have in terms of one of those variables, say. Then solve .
Find a vector in such that the vectors , , , and are orthonormal.
I know orthogonal vectors are those that if multiplied together equal 0.
I know that orthonormal vectors are vectors that are orthogonal and have a unit length of 1.
So will have to be able to be multiplied by and equal 0 in order to be orthogonal and then it must have a unit length of 1.
I just am not sure how to solve this type of problem
Thank you for any help
