I'm not sure how to prove that it is zero. I don't see what I can do after the second last step.

For a set to be orthogonal, it means that all of its elements are mutually perpendicular to each other. In other words, the dot product of any two elements in the set is equal to zero.
To prove that a set is orthogonal, you must show that the dot product of any two elements in the set is equal to zero. This can be done by finding the dot product algebraically or by showing that the angle between the elements is 90 degrees.
Yes, a set can be both orthogonal and linearly independent. Orthogonality refers to the relationship between the elements, while linear independence refers to their individual linear combinations. A set can have both properties at the same time.
Having an orthogonal set can make mathematical calculations easier and more efficient. This is because the dot product of any two elements in the set is equal to zero, which simplifies many equations. Additionally, orthogonal sets are often used in applications such as signal processing and data compression.
Orthogonal sets have many practical applications, such as in signal processing and data compression. In signal processing, orthogonal sets can be used to efficiently represent and analyze signals. In data compression, they can be used to reduce the amount of data needed to represent a signal or image without losing important information.
