1
切线, 切線
a straight line that touches a curve or surface at exactly one point, known as the point of tangency
- In geometry class, we learned how to draw a tangent to a circle, ensuring it only touched the circle at a single point.
在几何课上，我们学习了如何画一个圆的切线，确保它只在一点接触圆。
- The artist's sketch showed a spiral with multiple tangent lines, illustrating the various points of contact.
艺术家的草图显示了一个带有多个切线的螺旋，说明了各个接触点。

正切, 切线
(mathematics) the ratio of the opposite to the adjacent side of a triangle that has one angle of 90°
- If the tangent of an angle is 1, it means the height and base of our triangle are the same.
如果一个角的切线是1，这意味着我们三角形的高度和底边是相同的。
- When the sun is setting, you can use the tangent to figure out the angle the sun makes with the horizon.
当太阳落山时，你可以用切线来算出太阳与地平线形成的角度。
