I found myself stupid! Always do bad things! It s stupid to install a new machine!

Are you playing with the computer or being played by the computer, my experience is that you have to buy a computer at one time, don't think about what parts to save and upgrade, and when you want to upgrade, it is estimated that the whole machine will have to be replaced.

1: Although the old power supply and the new power supply are both 300W, the 12V output, direct AC conversion rate, etc. are not the same as the new one, and the new power supply is obviously more sufficient, and it is also more power-saving... Do you know the tiered electricity price?

2: The chassis of the brand machine are relatively small, because the graphics cards of the brand machine are very small (of course, the performance is the same thing), so your brand chassis may not be able to fit the current luxury large board + luxury large board card.

3: The memory of the old host is worth 50, the monitor is worth 50, and your hard drive is still broken. Everything else is not necessarily worth much, and you can sell it for 200 which is already sky-high.

When you're ready to go to college, you can allow yourself to be stupid and naïve, and think about how your life would be complete if you didn't have this kind of stupidity.

Four years of college, the computer and I are so close to you, your computer will be your best friend in college, cherished.

There is often a second-hand market in the university, and I can resell it when you arrive, and once I sold it for 5 yuan for 15 yuan.

Don't worry, you won't lose.

400 yuan to see the opening point, two dates are this number, I wish you a wonderful university!

I don't know what you want.

I upgraded the host to replace all the old set of internals, bought a new thin-skin chassis, put this set in, and finally sold it for 1000 yuan, and it didn't come with a monitor. But my old set, playing Call of Duty 6 won't get stuck.

The new accessories use a 700W power supply, which is less than 300 yuan. Think about it before installing the computer, and then move it, and it won't pass the expiration date if you put it away.

If there are three packs, return it.,400 yuan 300W power supply is not wrong,Antek 400W is only about 300,Anyway, Intel will be cheaper in the future.,It's just right to buy it in a few years.。

Tell you not to regret what you have done, since you have done something wrong and then regret it, isn't it wrong to add to wrong? Isn't it fun to play with a new computer? Cool, right? Then don't think about the old one, since it's already sold, forget about it! Why bother with yourself.

There's no way.,The landlord has to be a little better in the future.,Don't be stupid.。 Remember!!

It's already like this.,Just let it be.,I took a good camera apart a few days ago to see.,It's broken.,Isn't this also going to be a new one?

As for the brand machine, except for the processor, there is nothing good, and if it is sold, it is sold, and there is nothing to be depressed about.

It's good to buy the new one to a friend, and you can earn it back, and your friend doesn't have to make money for the merchant, how good it is, and it's even better to sell the old one to a friend.

There is a formula for this simplification of trigonometric functions: for example, the simplification of y=asinx bcosx, (a, b are constants) then a common factor is proposed, which is equal to [the square of a plus the square of b] under the root number, and now look at the question you asked, where a=1, b=1, so propose (root number: I use instead of) 2 get:

2 [( 2 2)sinx ( 2 2)cosx], because sin45 degrees or cos45 degrees = 2 2, so the above formula is 2 2 (sinxcos45 cosxsin45), and then the identity transformation of trigonometric functions (if you don't remember, go to compulsory 4) can get y= 2sin (x 45 degrees). Hope it helps you :).
