The number 𝑖 is defined as the square root of -1. Since 𝑖 doesn't exist anywhere on the number line, if we want to represent it, we need to create a separate axis for it, known as the imaginary axis ...

Modern complex industrial processes are increasingly integrated and automated. There are numerous control loops in the processing system, and the closed-loop feedback makes units strongly coupled.
Draw the graph of \(y = x^2 -x – 4 \) and use it to find the roots of the equation to 1 decimal place. Draw and complete a table of values to find coordinates of points on the graph. x ...
