All kinds of parameters can be described using complex numbers of the form real + j * imaginary. The numerical values of real and imaginary can vary over very wide ranges. Trying to graph them ...

As a tangent is a straight line it is described by an equation in the form \(y - b = m(x - a)\). You need both a point and the gradient to find its equation. You are usually given the point - it's ...

A tangent to a circle at point P is a straight line that touches the circle at P. The tangent is perpendicular to the radius which joins the centre of the circle to the point P. As the tangent is a ...
