Two examples are \(y = 3x - 2\) and \(y = 3x + 11.6\). Find the equation of a straight line that is perpendicular to \(y = 2x + 1\). The gradient of \(y = 2x + 1\) is 2. The reciprocal of 2 is ...

Perpendicular lines will always cross at right angles. To determine if two lines are perpendicular, we need to multiply their gradients together. If the lines are perpendicular to each other ...

Also called "vertical recording," Toshiba and Seagate introduced perpendicular recording drives in the 2005-2006 time frame. Other vendors followed, and densities reached 400 gigabits per square ...
