the position B after moving through the velocity vector. However, this move will not proceed smoothly, because we found that a collision occurred. The collision point is in the red area, that is, the intersection of the velocity vector and the boundary line. Our next job is to calculate the intersection. This is a process for Solving Linear Equations, so we will use the same tool...

The first thing to note is that this rule

effects themes is quite complicated. If you have no patience, forget it. Also, see the following video card support range. If the performance is lower than 9800, I suggest you do not install it. The effect will certainly be achieved, but it is very resource-consuming. for a reference, my X800GTO (256 MB/256bit) is not very smooth. Measure it by yourself. I personally think that the X1600 or above should be smooth.I. First install the graphics card dr

But it also brings about some problems, such as restarting X-Window and slowing down, but it solves the problem that the lower right corner of the page is not normal for a long time. I will not comment on my personal wishes, only the installation steps are provided:
In addition, GNOME is recommended for the desktop environment. In my personal test, I think 3D is not very stable in the KDE environment.

I added a condition that is more than 9800 pixels in size. As a result, "H" was found.
You asked me how I counted 9800? Estimate, but what I'm trying to say is not the area, and the use of the area is just one way. There are many ways to determine more precisely.

However, if you insert several rows above line 12th and then enter data in the newly inserted blank cell, the original function formula =sum (A2:A11) does not change, so the newly entered data c
