Furthermore, the absolute value of the velocity vector is the speed vector of the curve, meaning $$\left | \frac{d\mathbf{r{dt} \right | = \frac{ds}{dt}$$. So the formula. Consider a plane curve defined by the equation y=f(x). Suppose that the tangent line is drawn to the curve at a point M(x,y). The tangent forms an angle α with. 18 Useful formulas. Sometimes it is useful to compute the length of a curve in space; for example, if the curve represents the path of a moving object, the length of the curve between two points may be the distance traveled by the object.

Because tangent lines at certain point of a curve are defined as lines that barely touch the curve at the given point, we can deduce that tangent lines or vectors have slopes equivalent to the instantaneous slope of a curve at the given point. So the formula for unit tangent vector can be simplified to: Curvature of curvature formula Curve Curvature is a measure of how curvature formula the curve deviates from a straight line. This means a normal vector of a curve at a given point is perpendicular to the tangent vector at the same point.

Mean curvature was the most important for applications at the curvature formula and was the most studied, but Gauss was the first to recognize curvature formula importance of the Gaussian curvature. Due to the nature of the mathematics on this site it is best views in landscape mode.

We might still imagine that the curve represents the position of a moving object; now we get the position of the object as a function of how far the object has curvature formula.

We know that this curve is a circle of radius 1. The simplest form of curvature and that usually first encountered in calculus is an extrinsic curvature.
