The Equation of a Tangent Line:We can find the equation of a tangent line of an arbitrary line if we known the slope of the line and the coordinates of a point that lies on the line. The slope of a tangent line to a...
Point on a Curve: Suppose the equation of a curve and a point not necessarily on the curve are given. To check whether the point lies on the curve, we may substitute the coordinates of the point in the equation of the curve. If ...
