Dec 27, 2013 · A "rise" with "run" amount to find the degree of elevation is a simple Tangent formula relationship. Tangent of an Angle = rise / run. 1 unit of rise for every 1 unit of run is equivalent to the tangent of 45° (or 100% grade in road construction) If two of the three unknowns are given you can solve for the third.

就是我的页面上有一个textBox，我要实现在其中输入一些数字后按回车触发执行操作，关键是如何实现按回车触发，求大牛指点 And since multiple angles may have the same sine (e.g. 59° and 121°), it seems useful to see the numerical progression of the functions in addition to their graphical representation. Here is a printable sine-cosine-tangent table for all integer angle values in degrees, from 0° to 360°. Page 1 holds 0° to 180°; page 2 shows 181° to 360°.
