It's important to know that, like cars, lawn mowers need constant maintenance in order for them to work properly through the years. One of the most shared aspects between cars and lawn mowers is the oil. Knowing how to change the oild is very important and not doing so can lead to a machine that has to work twice as hard and can break easily. So in this tutorial, you'll be finding out how to change the oild on a John Deere X320. It's easy to follow and easy to do. Enjoy!
The relationship and the definition of derivatives and anti-derivatives is described in this video. First, consider a function F(x)=x^3-5x+2 and another with small 'f', f(x)=3x-5. f(x) here is the derivative of F(x). However, on the contrary, F(x) is said to be the anti-derivative of f(x). There is a catch though; even though F(x) has only one derivative in the form of f(x), f(x) here has more than one anti-derivative. This is because f(x)'s anti-derivatives are of the form F(x)=x^3-5x+c, whe...

In this video the instructor shows how to do temperature conversions using y = m*x + b. Now if Celsius is represented by the variable C and Fahrenheit is represented by the symbol F, you can replace then in the previous equation in place of the variables x and y giving you the equation C = m*F + b. Now to solve for the values of the constants m and b you need to have values of two sample temperatures in both Celsius and Fahrenheit. Take the first sample and substitute in the above equation gi...
In this video the instructor teaches about direct and inverse variation. Two variables x and y are said to be in direct variation with each other if you can write them in the form y = K * x. The value of y varies directly corresponding to the value of x. Y is said to be directly proportional to x. If you have a sample value of x and y, you can substitute the values in the above equation to compute the value of the constant K. Using this formula you can always find the value of one variable x ...
This video shows us how to draw a linear equation using the slope and intercept technique. First, the narrator explains how to simplify the equation in order to get the slope and intercept out. He then shows how the coefficient of x equals the slope and the constant term tells us the y position of the intercept point. The technique for drawing the final line is plotting the intercept at the right height on the y axis, then running for some distance along the x axis and rising some amount. Thi...

In this video the instructor shows how to find the slope of an equation which is in the form Ax + By + C = 0. He says that the formula to find the slope of a line in the above form is slope m = -A/B, where A and B are the numeric constants of the variables x and y in the given equation. He goes on and further shows how to do this with a couple of examples. He shows how to reduce any equation into the general form and how to apply the slope formula then. This video shows how to find the slope ...
In this video tutorial the instructor shows how to solve a single-step equation by taking the reciprocal. He says that in the equations of fractions containing a variable on the one side, you multiply the reciprocal of its numerical constant to it so that only the variable x stays out. Similarly we need to multiply the reciprocal value that we used on the left hand side on the right hand side too to maintain the equality. Now after simplification as only x is left on the one side we get its v...
In this tutorial the author explains the concept of Newton's Second Law of motion which states that force is equal to mass times acceleration. So the equation to compute force F is F = m * a, where m is the mass of the body and a is the acceleration produced by the force on that body. He explains that even our weight is our mass times the gravity. So now he explains that mass of a body is constant and only our weight changes depending up on the situation we are in. If you want a clear underst...

The trick in the video is that the magnets are made of a conducting material and they connect the battery terminals to the copper wire, so the battery, magnets and copper wire make a circuit that generates a magnet field just in the vicinity of the battery. The geometry means the two magnets are automatically at the ends of the generated magnetic field, where the field is divergent, so a force is exerted on the magnets.

When it comes to winter weather, the garage should not be neglected, especially if you have a room directly above it. Neglecting to properly insulate and seal your garage doors will create a constant rush of cold air inside, making the garage really cold, in turn making the floor upstairs really cold. This will drive up your gas or electric bill in no time during the winter months. But you can fight higher heating costs with some DIY ingenuity, and Dave Mars will show you how!
Micro misters allow for low volume of water over a wide area. They give good moisture coverage. Systems can be pulled up, changed and made into what you need it to be. Keep potted plants separate from other plants. They should have their own system. There is a system to encourage growth of root systems of various plants. Shrubs get two emitters in case one clogs up, the plant still has moisture. Having the water at the base of the plant limits weed growth. There is a temporary system to get t...

Rick Pitts takes us through how to do a push up using a coffee table. First, he starts by doing a push up for shoulders and triceps. You do this by placing your hands slightly wider than shoulders with fingers pointing forward. Keep your elbows near body as you lower yourself towards the table.
First of all you have to loose the altitude by taking a circle or two around in the air. On the final turn make a good straight approach to runaway and don't use too much ‘ailerons’ then. Just use the controls ‘rudder’, ‘elevator’ and ‘throttle’. Also watch for the cars or the traffic where you are going to land. Keep constant low ‘throttle’. You have to maintain good ‘idles speed’. You might want to adjust and remember the trim settings. After touch down, don’t pull on elevator. Just cut the...
This video shows you how to find the antiderivative of a function. By definition, the F(x) is an antiderivative of f(x) means F’(x) = f(x). The small f is a derivative of the capital F, and the capital F is an antiderivative of the small f.
