Last week my keyboard got unplugged but it would not work after plugging it back in. After doing some research, the keyboard that I use involves a PS/2 connector which is not hot swappable. This means that the keyboard can not be plugged and unplugged without turning the computer off. Thus I had to turn off my computer (and unplug the power to the computer) before plugging in the keyboard and then turn the computer on. The keyboard has worked since. The PS/2 connector is usually used for older keyboards so if you have one this video can save you some time (and frustration). Newer keyboards that use a USB connection are hot swappable and thus you don't need to turn the computer off when unplugging it. This video is also applicable to Mouses with a PS/2 connector.
In this video I go over the last 3 main coincidences covered in my earlier video, and these are: Republican Steve Scalise getting shot on June 14, 2017 at the same time that the Grenfell Tower was on fire in London, and Donald Trump getting arraigned on June 13, 2023 on the eve of his 77th birthday. The alleged Steve Scalise shooting was during a the annual Congressional baseball game and the shooter was a supposedly a "left wing extremist"; mirroring the usual "right wing extremists" propaganda. Of note is that Steve Scalise still says Trump rightfully won the 2020 U.S. election. The Grenfell Tower building fire was the worst residential UK fire since World War 2 (WW2), yet the fire was not able to turn the towers to dust like on 9/11. Lastly, Trump was arraigned this year on for the "Mishandling Classified Documents" saga aka psychological operation (PsyOp) aka massive useless distraction.
With the constant news of Trump getting indicted and arraigned for multiple charges, including for the infamous January 6 2021 "insurrection", it appears possible that Trump may campaign from behind prison walls, and possibly even do debates from there too. Truly a clown world circus, but nonetheless should be entertaining, especially if Mrs. Hillary Clinton Body Count ends up running against Trump! What a time to be alive!

In this video I go over Part 3 of the Laboratory Project: Bezier Curves. In this part I look at Question 3 of the project, which looks at moving the second control point in hopes of obtaining a loop within the Bezier curve. I test out different values for the second control point and after experimenting, it appears that in general moving the right of the third control point creates a looped Bezier Curve. What’s also interesting is that the findings of Part 2 hold true for this looped curve, in that the tangent lines at the first control points still pass through the second control point; and like-wise the tangent line at the fourth control point passes through the third control point. This is a great video to understand how manipulating the control points changes the resulting curve in a controlled way, hence the name “control”. This behavior is why the Bezier Curves are used in many computer-aided design technologies, including simply printing letters. I will illustrate this even further in later parts, so stay tuned!

In this video I quickly go over how to verify if our 3D to 2D projection is correct, which I do so by adding sight lines in GeoGebra. These "sight lines" are just lines drawn connecting the coordinates of the camera and the projected points on the screen. If these sight lines intersect our clipped points along the 3D line, then it means our projection is indeed correct. This is because the clipped points are simply projected along a straight line from the camera to the screen. In the amazing GeoGebra 3D graphing calculator, we can quickly create sight lines by using the line segment function: https://www.geogebra.org/calculator/twezjbu5

In this video I go over another example on Linear Differential Equations and this time solve the initial-value problem: (x^2)y' + xy = 1, given that y(1) = 2 (and x is positive). In this example, we first have to write the equation in the standard linear equation form of y' + P(x)y = Q(x). From there it is standard procedure to solve for y(x). Also in the video I plot the solution as well using L'Hospital's Rule to determine the limit as the x approaches infinity. This is a pretty interesting video on the procedure on solving linear differential equations, so make sure to watch this video!

In this video I go over a very important example on finding the intersection points of two polar curves, which is essential when determining the area bounded by two polar curves. This example involves finding the intersection points of the circle r = ½ and the four-leaved flower r = cos2ϴ. We can find 4 of these intersection points by setting the two equations equal to each other. But when we graph the curves using the amazing Desmos calculator, there are in fact 4 additional intersection points! This is because, as illustrated in my earlier video on the area bounded by two polar curves, the points of intersection can occur at different “times” or at different values of ϴ for each polar curve. But in this video I show that we can use symmetry of the curves to find the other 4 points, but also by noticing that the circle r = ½ can also be written as r = -1/2. Since r in polar coordinates is just the distance from the origin, whether r = +1/2 or -1/2 we get the same curve. When we set r = -1/2 equal to the flower r = cos2 ϴ and solve for the ϴ we in fact obtain the 4 additional intersection points. This is a very important video in that it illustrates the steps to take to find some of the intersection points of polar curves that are not so easy to solve, so make sure to watch this video!

In this video I go over asymmetric catenaries which are just catenaries but hung at different heights as opposed. I was recently asked whether the curve formed by hanging a cable across two different heights was the same as that for when the heights are identical, and so I looked into this question further to realize that yes, yes it is. The reason for this is that in my earlier derivation video on catenaries I set up the coordinate system so that the lowest point on the catenary is located at the y-intercept, and then set up a free body diagram of the a segment of the rope or cable. The free body diagram illustrates the tension in the rope at the lowest point and the linear weight density as the only physical constants that need to be obtained, and thus the derivation does not include the actual heights at which the catenary is hung. Thus the resulting hyperbolic catenary function y = a*cosh(x/a) + c is the for both asymmetric and symmetric catenaries! The only difference is that the location of the lowest point of the curve, and tension at that point may change at different heights.
Also in this video I go over a couple of applications of the catenary functions, including catenary mooring line systems and the Sea-To-Sky Gondola transportation service for mountain climbers. This is a very interesting video illustrating varying types of catenaries and how we can always look to the original derivation of to see how the resulting shapes will be like, so make sure to watch this video!

I always thought that drinking beverages that contain caffeine such as coffee and tea dehydrate you and thus you shouldn't count them as part of your water intake. Caffeine is considered as diuretic, meaning it increases urination, but is this true for regular caffeine intake? After doing some research it appears there is no evidence for this and regular caffeine intake does in fact count towards water intake.
