The straight line through two points will have an equation in the form \(y = mx + c\). Then, we can find the value of \(c\), the \(y\)-intercept, by substituting the coordinates of one point into the ...
Reflect the shape in the line \(x = -1\). The line \(x = -1\) is a vertical line which passes through -1 on the \(x\)-axis. The line \(y = 1\) is a horizontal line which passes through 1 on the ...
We study the solvability of the equation AX + XA * = XA + A * X = I. In particular, we obtain various criteria for the normality of A in terms of Hermitian solutions of the equation which satisfy ...
