A daughter gets an X chromosome from her mother and an X chromosome from her father. Suppose the X chromosome from her mother has the gene for normal blood clotting. Suppose the X chromosome from her father has the gene for hemophilia.
By Kardi Teknomo, PhD. A matrix is orthogonal if the transpose is equal to its inverse, that is. Since computing matrix inverse is rather difficult while computing matrix transpose is straightforward, orthogonal matrix make difficult operation easier. Orthogonal matrix is important in many applications because of its properties. Example:
an orthogonal projection. ( 1 of a system of real functions) defined so that the integral of the product of any two different functions is zero. ( of a system of complex functions) defined so that the integral of the product of a function times the complex conjugate of any other function equals zero.
