A tangent line t to a circle C intersects the circle at a single point T. For comparison, secant lines intersect a circle at two points, whereas another line may not intersect a circle at all. This property of tangent lines is preserved under many geometrical transformations, such as scalings, rotation, translations, inversions, and map ...
The curve itself is the curve that is tangent to all of its own tangent lines. It follows that = {(,): =} . Finally we calculate E 3. Every point in the plane has at least one tangent line to γ passing through it, and so region filled by the tangent lines is the whole plane.
Examples of osculating curves of different orders include: The tangent line to a curve C at a point p, the osculating curve from the family of straight lines. The tangent line shares its first derivative with C and therefore has first-order contact with C. [1] [2] [4] The osculating circle to C at p, the osculating curve from the family of circles.
The tangent line is said to be "going in the same direction" as the curve, and is thus the best straight-line approximation to the curve at that point. The tangent line to a point on a differentiable curve can also be thought of as a tangent line approximation, the graph of the affine function that best approximates the original function at the ...
An osculating curve from a given family of curves is a curve that has the highest possible order of contact with a given curve at a given point; for instance a tangent line is an osculating curve from the family of lines, and has first-order contact with the given curve; an osculating circle is an osculating curve from the family of circles ...
An osculating circle is a circle that best approximates the curvature of a curve at a specific point. It is tangent to the curve at that point and has the same curvature as the curve at that point. [2] The osculating circle provides a way to understand the local behavior of a curve and is commonly used in differential geometry and calculus.
As shown above, if a circle is tangent to two given lines, its center must lie on one of the two lines that bisect the angle between the two given lines. Therefore, if a circle is tangent to three given lines L 1, L 2, and L 3, its center C must be located at the intersection of the bisecting lines of the three given lines. In general, there ...
Solutions to a slope field are functions drawn as solid curves. A slope field shows the slope of a differential equation at certain vertical and horizontal intervals on the x-y plane, and can be used to determine the approximate tangent slope at a point on a curve, where the curve is some solution to the differential equation.
