How To: Origami a Christmas star aka Spiked Dodecahedron (SPD)

The Origami Spiked Pentakis Dodecahedron is an excellent Paper Christmas Decoration Star made out of 15 paper squares. In spite of the large paper size I was defeated by the last module after nearly 2 hours (!) of trying to lock the last unit in place each time another one dislodged. Never mind, it is still a remarkable sound structure once (nearly) completed and you can not see which one is not locked anyway.

How To: Factor a trinomial by GCF then grouping method

This is a video tutorial in the Education category where you are going to learn how to factor a trinomial by GCF then grouping method. For example how to factor the trinomial 6r(squared) – 28r + 16. The first thing is to get the greatest common factor (GCF) of the numbers. So, GCF of 6, 28 and 16 is 2. The trinomial can now be written as 2{3r(squared) – 14r + 8}. To factor by grouping, see the trinomial as the general formula of ar(squared) + br + c. To factor this, you got to look at the...

How To: Cut floor joists to length quickly and accurately

Fine Homebuilding with Jim Anderson demonstrates how to cut floor joists to length. Inspect the rim line to know where to set the joists. Set the joists to the layout on the rim line using a two man team. Tap a nail into the joist to keep it from moving around. Instead of standing the joists up to square them, cut them on both ends. Line the chalk line up with the rim line and snap the line across the joists to mark them. This will simultaneously measure and square them. Finally, line the joi...

How To: Use the Chain Rule for finding derivatives

JustMathTutoring This video shows the procedure of finding derivatives using the Chain Rule. The Chain Rule states that the derivative of a composition of functions is the derivative of the outside function evaluated at the inside multiplied by the derivative of the inside. This can be stated as if h(x) = f[g(x)] then h'(x)=f'[g(x)]g'(x). This is explained by two examples. In the first example we find the derivative of the sine of square of 'x'. We take the derivative of sine at square of 'x'...
