The guy first gives the definition of differential equations. He explains that a differential equation is an equation that contains the derivatives of an unknown function. He then gives some examples of differential equation and explains what the equation's order means. After that he gives an example on how to solve a simple equation. He calculates it and gives examples of graphs. Then he explains what a general solution is and how to narrow down the number of solutions using data from the pr...
This video shows the method to use differential equations to represent growth. Consider the function y=multiple of C & e raised to kx or Ce^(kx). Differentiating it with respect to x, we get dy/dx=kCe^(kx) or ky. So, the solution of the differential equation dy/dx=ky is Ce^(kx). There are two possibilities in the function y=e^(kx). It can be exponentially growth or decay function. This depends on the value of k. If k is greater than 0 or k>0, we get an exponential growth function. On the othe...
Sewing with a serger sewing machine can be quite difficult, if you're lucky enough to own one. Even threading the beastly sewing machine can be pretty tricky. But this two-part video tutorial should help you to properly thread one. This covers the threading of a Singer Differential-Feed Finishing Touch serger sewing machine (14SH654), which has 4/3 thread capability. Singer also has a PDF available with detailed threading instructions.

In this tutorial, we learn how to change your differential oil on a Jeep Grand Cherokee. First, you will need to remove the drain plug from the underneath of the vehicle, then let it drain out onto an oil pan, use a pipe and pump to do this. Once it's finished draining, you will need to replace the plug. After this, grab a new pump and pour your new oil into the pump. Remove the plug again, then pump the oil back into the engine. Once the oil is full, you can replace the drain plug and check ...
In this how-to video, you will learn how to put back a 2 speed central gearbox in your RC vehicle. Take the time to clean your car. Remember that the shorter dog bone goes to the rear and the longer one goes to the front. Slide the dog bone in and make sure that it spins the wheels. Now, raise the dog bones and slide them into the drive cuffs of the central transmission. Once this is done, check by moving the tires to see if the gears are moving. Make sure the box fits into the place provided...

In this video, we learn how to backup your computer with an external hard drive. First, go online and download and install Cobian Backup. After this, start a new task on the program and then name it your computer backup. Change it to a differential and change the time frame to once every five times. Now, click on the file section and add the files you want to have backed up. If you want to copy your entire C drive, just highlight that. Now, the C drive will show up, then click add underneath ...
It looks like the dust is finally starting to settle on Google's POLED PR nightmare. The Pixel 2 XL — one of the most hotly-anticipated phones of the year — has been plagued by screen issues and worries. While it is certainly not without its faults, Google has created several software fixes and is offering a 2-year warranty for screen burn-in, so we can rest a bit easier about purchasing Google's latest Pixel.
One option you won't find buried in the Galaxy Note 9's Settings is the ability to return the navigation bar to black. Samsung changed the default color to white with the Note 8, removing any ability to bring the black color back. But thanks to a neat app, Note 9 users can do it themselves.
Google caught a lot of flak for the Pixel 2 XL's POLED display issues, regardless of whether the problems were real or perceived. It's too late to contract another screen manufacturer at this point, but Google is doing the next-best thing: Fixing as many user complaints as possible with software updates.
Android comprises an entire ecosystem of apps, games, functions, and features, so it would only make sense that it has its own lexicon. Words, phrases, and acronyms that didn't exist ten years ago are now used in an off-the-cuff style by developers and support technicians across the web.
It's not rare to see an advertisement in tech directly call out the competition. Whether it's the famous Mac vs. PC ads from back in the day or the Pixel burning the iPhone 7's lack of a headphone jack, rivalries in these commercials are certainly commonplace. Samsung's new ad campaign takes a more subtle approach to this "throwdown" advertising, but the message is still clear — Samsung wants you to know its AMOLED displays are better than Google's and LG's POLED.
We recently ran down several hidden features on the Galaxy S9 — items that are buried deep within the settings menu that can be tricky to find. One thing that many users cannot find is the option for a black navigation bar. Unfortunately, this option does not exist in Samsung's stock settings. But this is Android, so with a bit of developer magic, we can easily regain the black navigation bar in no time.
Action games encompass a wide array of categories, ranging from racing games that pit you against players the world over for track domination, to endless runners that push you to set ever higher scores, and RPGs that let you embark on adventures in fantasy worlds. With such a huge selection of titles to look through, it's all too easy to overlook a game you might otherwise like.
Privacy and security go hand in hand, especially for smartphones. When it comes to privacy, you decide what personal information about yourself is out there to discover. Security, on the other hand, is all about enforcing those privacy decisions.
This video is on how to install a Revo forward only (or FOC) for your radio controlled vehicle. For this, you will need to remove your 2.5 or 3.3 Revo transmission from the kit and then I will walk you through the rest. You will basically be removing the front gears and then replacing another gear towards the back. Also, I am using the center differential kit which is easier as you do not have to worry about the gearing on the center differential shaft. If you do not purchase the center diffe...
This video presentation details the process of calculating a handicap in golf, in this presentation the handicap will be calculated on the USGA handicap system which is the official handicap system to be used in the United States. On each score card, there is a designation for the handicap and slope, these numbers do not vary frequently between sixty-eight and seventy-four, and one-fifteen, and one-thirty, respectively. The 'Slope' is a new calibration that is used to help make a handicap fai...
Airsoft doesn't get any better than a cloud chamber BB machine gun, aka Cloud BBMG. This design has an incredible rate of fire. If you've got a full charge of compressed air, it can easily fire more than 50 rounds per second at a 350 ft/s muzzle velocity. Since this is a legit airsoft build, it should be handled safely with the same care as any other airsoft firearm, and you should be wearing the same protective gear—protective mask, safety glasses, etc. My video details the build of this bea...

Today, Null Byte will be covering how we can automatically, and efficiently back up our data across all OS platforms, while giving a few alternatives to the built-i...
From Jalopnik: The LOLrioKart is outfitted with..."a hundred pounds of Ni-Cad batteries in the lower tray, a crude steering rack up front, pneumatic tires all around and some power-electronics to control a 15 HP Etek pancake motor hooked to a sweet custom differential at the rear all good for a top speed of 35 MPH."
The 2011 Toronto International Scrabble Open (TOSI) took place last weekend, with former World Champion Adam Logan beating out all of the human competition for the $3,000 grand prize. But when it came time to take on the Quackle program in the Human vs. Computer Showdown, he lost his first two games and won the last two, ultimately losing with a measly 28-point differential of the combined total scores. But he still came out three grand happier.
