In this video I explore why the shape of cans that you see in the supermarket are the way they are and use calculus to determine what ratios of can height to can radius are used in real life. This is an applied project question in my calculus text book and I thought it was really interesting and worth doing a math easy on it! Enjoy!

In this video I go through a useful example on marginal cost vs average costs and show how to apply the principle which I proved in my previous video that the average cost is minimum when average cost equals marginal cost.

In this video I look further into economics and show that the average cost of producing one item when x items are produced is minimum when the average cost equals the marginal cost. This is an important principle to understand and it is easily derived using the calculus principles that I have covered in my previous videos.

In #MESExperiments 28 I demonstrate the amazing ability of the GyroTop magnetic spinning top to always balance opposite the magnetic attractive force even when turning the apparatus upside down. The GyroTop, also called Space Top, is the invention of an obscure person named Owen Liang, and whom created it to test his hypothesis that spinning tops want to align themselves opposite of gravity rather than simply "maintaining angular momentum".

The first part of the video involves just a regular spinning top with the ring magnet removed, and is used as a comparison. The spinning top keeps upright opposite the force of gravity even when the apparatus is tilted. This demonstration is often used to illustrate "angular momentum".

In the second part of the video, I attach the ring magnet and repeat the same procedure of spinning it up with a drill. Note the GyroTop has a tube to manually blow air into to spin it up, but I used my drill instead. As I rotate the apparatus the GyroTop always moves to align against the magnetic attraction. This is counterintuitive since the angular momentum should keep the top stationary until the magnetic attractive force is strong enough to grab hold of the top. This GyroTop opens up lots of possibilities!

Further information, screenshots, and relevant links are included on the Hive blockchain: https://peakd.com/hive-128780/@mes/mesexperiments-28-magnetic-spinning-top-aligns-opposite-of-magnetic-attraction

The timestamps of the regular vs magnetic spinning tops are shown below:

- Magnetic Spinning Top: 0:59

In this video I expand on the area of a triangle proof and show that regardless of the shape of the triangle the Area of the triangle remains the same no matter which side is used as the base. The formula for all cases still remains at Area = base*height/2.

In this video I go through a useful word problem and show how you can derive the demand and revenue functions for a simple consumer sales example. I also illustrate how you can increase revenue by offering rebates, or basically refunding a percentage of the product back to the buyer.

Ever wonder how your calculator is able to graph or find the roots of complex functions?? Well chances are, that your calculator either uses Newton's Method or a variation of Newton's Method. Note also that this method is sometimes called the Newton-Raphson Method.

In this video I show how you can use modern powerful spreadsheet capabilities to prove that pi is indeed 3.14... at least 2 decimal places. This is a pretty ridiculous method I just figured out which basically involves computing the area of many squares (or Microsoft Excel cells) inscribed inside a circle and using this area to compute what Pi should be.

In the examples I utilized Microsoft's powerful spreadsheet capabilities and use Excel tables to automate Newton's Method. I also show some useful tips on how to speed up creating a table in Excel.

Is your video too loud or too quiet?? Well if it is than you need to download Handbrake, which is a free program, from http://handbrake.fr and use it to lower or increase the audio volume in your video. In this video I show how you can easily do it with Handbrake.

My earlier video which was about my cousin, Simone, doing one-handed push-ups was initially way too loud and I needed to figure out a way to decrease the volume before uploading to YouTube. You can watch that video on the link below:

In this video I go over a very interesting concept and that is in interpreting complex or imaginary numbers as and equivalent rotational matrix form. This concept was brought to my attention by Lori Gardi from the Fractal Woman YouTube channel: https://www.youtube.com/user/FractalWoman/search?query=complex%20numbers

Rewriting complex numbers as rotation matrices allows for looking at complex numbers from a different perspective, and this case that perspective is in simply rotating vectors. The imaginary number "i" is thus viewed as simply a 90 degree rotation when viewed as a rotation matrix. I also rewrite the famous Euler's formula into a rotation matrix form and that turns out to just be a 180 degree rotation. Since complex numbers appear often in mathematics and physics, it may be insightful to reinterpret such complex equations as simply vector rotations!

Note that while I only covered 2D rotation matrices, a similar concept can be applied to 3D rotation matrices, and which I may cover in future videos so stay tuned.

In this video I recap what antiderivatives are which I showed in my earlier video and go through some very useful examples on antiderivatives. I also list a table of common functions and their antiderivatives.

In this video, I continue further on Antiderivatives and go over some further examples which include initial value problems that involve solving for the constants of the general antiderivative function. I also graph out the function and its antiderivative to show how the function can be used as a check of the antiderivative by looking at the inflection points and whether the antiderivative is increasing, decreasing, or concaving up or down.

You probably have used the foil method in Elementary and High-school math class but you may not know quite why it works. Well the proof is quite simple and it involves just considering the multiplication as an Area of a rectangle. Also in the video, I show a very quick method to foil out very complex equations and it involves creating a simple table and is very easy to memorize. If you don't know the foil method inside and out, then this video is a must watch since you'll have to use the foil method in almost every math, engineering, physics class.

In this video I go further into the wonderful world of antiderivatives and explore how we can apply the calculus graphing methods I showed in my earlier videos to graph the antiderivative a function without actually determining what the antiderivative is. I also show how you can graph the antiderivative in a very accurate method using the Directional Fields drawing technique which basically draws the tangent lines of the antiderivative at many x values and then graphing can be done simply by following the direction of the tangents and hence the name directional field.

In this video I go further into the examples series on Antiderivatives and basically show how they can be used to determine the position function when given the velocity or the acceleration functions and also initial position and velocity values. I also discuss gravity and how near the surface of the Earth the acceleration due to gravity can be taken as a constant which is equal to 9.8 m/s^2 or 32 ft/s^2.

My calculus book has some pretty challenging questions at the end of each chapter and I think it would be a good idea if I do some of those examples. In this video I go through a seemingly complex equation by showing that you can break it down into simpler terms and apply what we have learned in finding the local or absolute minimum or maximum to solve the problem.

In this video I introduce Sigma Notation and show how it is a really convenient method of writing down sums. I will be using Sigma Notation a great deal in my later videos on integral calculus, so make sure you watch this video to learn more about Sigma Notation or at least get a refresher if you have seen it before.
