Change your Microphone Volume Settings with Windows 7, 10, 11
If you have had some trouble hearing my voice in my other videos, it's because the default volume setting on my microphone was set to 50% for some strange reason. I had no idea before but I fixed the problem now so I made a Math Easy video on how you can easily change the volume settings on your microphone directly from Windows 7. Even if you have a program that can change the volume, make sure it actually changes the Windows 7 default settings because that is the most important. Also, the video shows how you can make your microphone a speaker phone by having your speakers play what you say. It's pretty amazing!
If you have a video with low volume already made, then you can still increase the volume of that video by using handbrake (see video link below).

In this video I first derive the formula for projecting a 3D point to a 2D screen and then apply that formula to the 3D line from the previous question. To project a 3D image onto a 2D screen, we just have to draw a line extending from the camera or viewpoint that intersects our desired point and extends to the screen. Then applying similar triangles, we can derive the projected coordinates for the y and z coordinates; note that the x-coordinates in this case all get projected to x = 0. Next we apply the derived formula to the clipped 3D line points from Question 1 to obtain the projected coordinates on the 2D screen. And as always, I graph this all out using the amazing GeoGebra 3D graphing calculator: https://www.geogebra.org/calculator/twezjbu5

In this video I go over the main assumption in the main paper on COVID-19 "virus" isolation, and that is the RNA extracted from patient and cell culture supernatants is assumed to be "viral". It took me a long time before realizing this since the paper does not state this directly. Instead, I had to ask ChatGPT to clarify a paragraph from the paper, as well as double-checking with the mainstream science literature. And indeed this is a key assumption made in virology in general. Ribonucleic acid (RNA) is supposedly the genetic makeup of the new SARS-CoV 2 "virus" which supposedly causes "COVID", so when a "viral infection" is suspected, then typically the assumption is that RNA found is from this "virus".
ChatGPT also outlines several methods to "confirm" this assumption, such as using PCR to detect specific RNA sequences, comparing the sequences with known "viral sequences", and "immunological assays". These assays use "antibodies" (or immune system "defense proteins") that are supposedly specific to and bind to proteins (called antigens) on the "virus"; thus allowing for indirect identification of this "virus".
All of this is interesting, yet it still remains highly questionable that a bunch of nucleotide sequences (aka RNA) are somehow assumed to be "infectious disease causing particles that can infect and replicate through a host and spread to other individuals (and even shut down the entire world)"...
The paper is listed below:
- A Novel Coronavirus from Patients with Pneumonia in China, 2019
- Authors: Na Zhu et al
- Published on January 24, 2020 in The New England Journal of Medicine (NEJM)
- https://www.nejm.org/doi/full/10.1056/NEJMoa2001017

In this video I go over Question 3 of the Laboratory Project: Taylor Polynomials, and this time revisit the quadratic approximation but instead use a slightly different notation. In Question 1 I illustrated how the quadratic or parabola or 2nd order polynomial approximation P(x) = A + Bx + Cx^2 can be used to approximate a function f(x) at x = a, with the conditions that P(a) = f’(a), P’(a) = f’(a), and P’’(a) = f’’(a). But in this video I show that it is often preferable to use a slightly different notation and instead use P(x) = A + B(x – a) + C(x – a)^2. The only difference in using this form is that the constants A, B, C will not necessarily be the same. This notation has the benefit in that determine the constants with the 3 conditions listed above is fairly easy because when we input x = a into P(x) or its derivative, most terms vanish because a – a = 0.
When we solve for the constants, I show that we obtain the function P(x) = f(a) + f’(a)(x – a) + f’’(a)(x – a)^2, which is a very convenient form to determine the constants, just from f(x) and its derivatives at x = a. Furthermore, this is the basis for Taylor Polynomials which I will be illustrating in further parts of this Laboratory Project, so make sure to watch this video and fully understand this concept!

UPDATE: Error at the end which I wrote f"(a)(x-a) instead the correct term of f'(a)(x-a).

In this video I go over tetrahedral numbers and provide a proof of their formula using mathematical induction. This video was requested by Dominic from Strode College in the UK, and is a good follow-up from my earlier video on the sum of consecutive integers.
A tetrahedral number is a number that can be visually represented as 3 sided pyramid, that is a tetrahedron. For example the numbers 1, 4, and 10 can all be visualized as a stack of balls in a tetrahedron pattern. In fact, the tetrahedron is just the sum of consecutive "triangular numbers", which are numbers that can be represented by an equilateral triangle.
I cover triangular or triangle numbers as well, and show that their formula is the sum of n consecutive integers. Finally, I use the triangle number formula as well as the principle of mathematical induction to prove the formula for a tetrahedron number. This was the first time I had learned about tetrahedron numbers so this was an interesting topic to cover. If you have any other video requests please let me know and I may cover it!
The topics covered as well as their timestamps are listed below.

1. Shoutout to Dominic from Strode College: 1:22
2. Tetrahedral Numbers: 2:26

In this video I prove the distance formula between 2 points in both two and three dimensions. The distance formula in 2D is readily derived using the Pythagorean theorem. In 3D we can extend the 2D distance formula by drawing a box and then applying the Pythagorean Theorem twice. Both distance formulas appear identical but with the 3D formula having the term in the z-axis. I also go over a quick example on calculating the distance between 2 points in 3D space.
The timestamps of key parts of the video are listed below:
- Distance Formula in 2D: 0:00
- Distance Formula in 3D: 1:49
- Example 4: 12:28

In this video I go over Part 5 of the Laboratory Project: Bezier Curves, and this time show how we can combine multiple Bezier curves to obtain even more complicated shapes. In this part I use the letter “C” curve formed from Part 4, and then duplicate it and modify it so that we obtain a letter “S”. This requires having two different sets of parametric curves but sharing one particular control point. To ensure that the “S” curve has a smooth transition at the connecting point, we need to ensure that the tangent lines match up at both points. We can do this by manually moving the control points around until obtaining a symmetric curve, or can even calculate the distances to ensure the tangent lines do indeed match. Also, as always in this Laboratory project, I show how we can manipulate the curve using the amazing Desmos calculator to obtain some pretty amazing shapes. The Bezier curves, and multiples of and variations of, are used in many computer-aided design applications, including laser printers, and even the letters and symbols you see on your screen right now! So it is important to understand just how these Bezier curves are formed and manipulated, so make sure to watch this video!

In this video I go over the Microsoft OneNote program while using the Microsoft Surface Pro tablet PC. OneNote is part of Microsoft's Office Suite and is very useful for taking notes on just about any topic. When combined with the amazing pen and writing abilities that the Surface Pro provides the OneNote program can literally replace all paper notes. It has for me and I recommend you get the Surface Pro and the OneNote program!
