When dealing with standard vectors (with purely real elements) we are used to finding the angle between the vector from But what happens when we are dealing with vectors that have complex elements. In quantum mechanics, in general, the inner product is a complex number, which does not define a real angle The Schwarz Inequality helps us in this regard However, according to it, the only thing we can know is that the absolute value of the inner product is...

Functions can be thought of as elements of a vector space. When we have two functions, we will make a 2x2 matrix of functions here the first row is the original functions and the second row are the first derivatives of the original functions. With three functions, we have two more rows, the first derivatives in row two and the second derivatives in row three. The matrix form is called the Wronskian. If you take the determinant and it is...
