tangent angle造句

例句与造句

1. One of my projects involves fitting an arc to the tangent angles and curvatures of given endpoints.
2. Curvature, as you know, is the first derivative of tangent angle with respect to arc length.
3. The lhs can then be evaluated using the tangent angle addition formula; you should get \ frac { m + n } { 1-mn } after canceling tans with arctans.
4. Euler's spiral is the curve in which & kappa; & prime;, the first derivative of curvature ( = second derivative of the tangent angle ) with respect to arc-length, is constant.
5. That lets you immediately figure out the tangent angles ( i . e . 90 degrees away from A and B respectively ) and compare them to the vector AB as expressed in polar coordinates . talk ) 14 : 53, 6 March 2010 ( UTC)
6. It's difficult to find tangent angle in a sentence. 用tangent angle造句挺难的
7. :: My na飗e suggestion : Cut up your original curve so that there is a control point wherever the tangent angle is a multiple of & pi; / 4, and wherever the curvature reaches an extreme or crosses zero; these are the points most important to the appearance of the glyph.
8. One speaks also of curves and geometric objects having " k "-th order contact at a point : this is also called " osculation " ( i . e . kissing ), generalising the property of being tangent . ( Here the derivatives are considered with respect to arc length . ) 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, and has second-order contact ( same tangent angle and curvature ), etc.
