I m going to buy a laptop tomorrow and test the hand held software and add 50 points after I m satis

Mobile Mark also offers a feature called the Reading Test, which mimics the user's ability to read a text file page by page, and his test results indicate how long your laptop battery will last under minimal load.

In addition, software such as Battery Eater and Battery Mark are also used to test laptops.

It's easy to use, just run it.

There is also CPU-Z, which shows the machine configuration and model.

3DMs 2003, 2005, 2006, 2007 are OK. Check the performance of your graphics card.

PCMark to check the performance of memory, CPU, and hard disk.

Windows Optimizer is enough.

Other testing software is mainly to test the authenticity of the hardware, and there is no need to test if you buy a brand machine.

Hardware test: SISOFT Sandra Pro 2004 test screen Nokia Monitor Test Battery: Batterymark

Test CPU: CPU-Z

Don't stress too much Anyway, when the time comes, we just need to fill in all the knowledge we know,,, too much nervousness will affect the performance

It's too late, it's best to relax and rest. Don't let ** take a chance.

everest is a very versatile tool to monitor hardware performance temperature changes on the Huidong Dott network, guess one in front of you.

Everest Ultimate Edition can realize hardware monitoring and real-time temperature testing I'm just hand-rolling dell notes **There are too many addresses Any** Hu Gao who has more than enough to do after the station is finished.

It's all pretty much the same, depending on what you like. However, the statement of the measurement type is incorrect. Handsets are not measurement GPS.

2x +8mx + 2m-3=o is found to be the intersection point of the x-axis, but not necessarily the vertex is on the x-axis.

The vertex is on the x-axis, which means that there is only one intersection with the x-axis.

So the discriminant formula b -4ac=0

2m-3 indicates the intersection of the image with the y-axis, and it does not necessarily have to be 0

b2-4ac=0 is correct because the vertices of the image are on the x-axis, so the image has only one intersection on the x-axis.

joke'Tomorrow you take the exam, you have to keep your word :)

Why didn't you nod your head? The quadratic function of the opening upward will always have an intersection point with the y-axis, and the opening direction is to see whether a is greater than or less than 0, and the a=2 of this function.

Because it is a quadratic function, it is necessary to use the discriminant formula b -4ac

The discriminant formula b -4ac=0 determines that the equation has 2 equal solutions, so the vertices are on the x-axis.

Take a walk around the boundary of the area to be measured by GPS guard, and you can get the area! GPS now should have this feature.

There are many simple area measurement handheld, such as Tianxiang 500 can be used, Chinese interface, easy to learn and use, accurate area calculation, local unit conversion, ** is also very cheap!

Take a look at Garmin or Magellan's handhelds, many models have this function, and the area measurement is as long as you walk around the place you want to measure.

Tool: Zhonghaida handbook.

Shortcut: GIS

First, a parametric calculation is performed based on the given three exact known points, a three-parameter elevation, or a seven-parameter calculation.

Second, the parameters of the proceeds are applied to the coordinate system.

Click on the broken step measurement in the lower left corner to create a layer and collect the broken steps around the desired area.

Click on the layer of the collected points; Select the figure. Use the auxiliary tools in the lower left corner to calculate the area.

It's actually very simple, the key is the application.

Give points

Generally, there are two ways, one is to measure the area of the route, and the other is to measure the area of the track.

I don't know which model of that brand you use, I generally choose handheld GPS, I recommend choosing a big brand, after-sales service, and the quality of the machine is more.

Let the resistance of the power tool be R1

A power tool, a known resistance R2 (R2 must be large enough), and a battery connected in series, and then measured in volts to obtain the voltage of the power tool and the known resistance V1 and V2 respectively.

i=v1/r1=v2/r2

Therefore r1=r2v1 v2

The multimeter can't be measured directly.
