Q:已有一条曲线,如何画出曲线上任意点的切线?

A:Origin 2016提供APP:Tangent供用户快速画出曲线上任意点的切线。用户可执行:

1.下载App:Tangent后将其拖入Origin,然后在Origin窗口右上方即会出现Tangent的图标

2.点击Tangent按钮打开对话框,完成自定义设置后点击OK,图形上就会出现一条垂线。
3.点击垂线下方的三角标,移动垂线寻找需要画切线的点,切线会跟随垂线的移动而移动
4.点击图中右上方的三角标,选择New Output可固定选中点的切线于图上
5.移动鼠标到曲线上另一点,点击Tangent按钮,即可新增另一条切线到图上
6.点击图中右上方的三角标,选择Preferences可重新打开Tangent的对话框,对其进行自定义设置
