Calc – Optimization II

Mr.Andrejkovics@gmail.com (Mike Andrejkovics) — Sun, 06 Dec 2015 22:26:13 +0000

In this video I take you through another classic Optimization problem for any first year Calculus student, optimizing the volume of a geometric solid subject to some condition. In this case, we are optimizing a Cylinder within a Cone. This is the second of two videos I have made so far on Optimization.

Calc – Optimization I

Mr.Andrejkovics@gmail.com (Mike Andrejkovics) — Sun, 06 Dec 2015 22:23:57 +0000

In this video I take you through a classic Optimization problem for any first year Calculus student, optimizing the area of a fenced in region. This is the first of two videos I have made so far on Optimization.

Working With Isosceles Triangle Theorems in Proof

Mr.Andrejkovics@gmail.com (Mike Andrejkovics) — Tue, 01 Dec 2015 21:56:22 +0000

Isosceles triangles come up in many different ways when we’re working with Geometric Proofs. They are of particular importance when you begin your study of Circles and the many Circle Theorems. In this video I will introduce you to the two Isosceles Triangle Theorems, as well as take you through two proofs that make use of the theorems.

Curve Sketching

Mr.Andrejkovics@gmail.com (Mike Andrejkovics) — Fri, 20 Nov 2015 13:52:11 +0000

An introduction into the time-honored tradition of curve sketching. Before we had Desmos.com, and HD Full Color computers in our pockets, we had the first and second derivative! Learn how to use the information obtained from the derivatives to sketch a polynomial function.

Working with Linear Pairs in a Two-Column Proof

Mr.Andrejkovics@gmail.com (Mike Andrejkovics) — Tue, 17 Nov 2015 21:05:17 +0000

This is a very short video taking you through the steps necessary to identify, and then take advantage of linear pairs in a proof. Using the theorem that “the supplements of congruent angles are congruent,” we can prove angles congruent under the right circumstances.

Construction: Dilation by a scale factor of 5/3

Mr.Andrejkovics@gmail.com (Mike Andrejkovics) — Fri, 10 Apr 2015 21:25:44 +0000

In this video I take you through the construction of a dilation in the plane with a scale factor of 5/3. You will need a compass and straightedge to follow along.

Construction: Dividing a segment into a given ratio

Mr.Andrejkovics@gmail.com (Mike Andrejkovics) — Mon, 30 Mar 2015 22:38:36 +0000

In this video I will take you through the construction steps to divide a given line segment into a specific ratio. I will construct two different ratios in this video, the technique is essentially the same for any ratio. You will need a compass and straightedge to follow along.

Construction: Dilation in the plane from an external point

Mr.Andrejkovics@gmail.com (Mike Andrejkovics) — Tue, 24 Mar 2015 22:56:00 +0000

In this video I take you through the construction of two dilations in the plane. The first, a dilation by 2, and the second, a dilation by 1/4. You will need a compass and straightedge to follow along. These are both basic dilations- look for my next video to learn a more sophisticated technique that will work for any scale factor (such as 2/3 or 8/5, etc).

Construction: Rotation about a fixed point

Mr.Andrejkovics@gmail.com (Mike Andrejkovics) — Sun, 22 Mar 2015 03:10:28 +0000

In this video I will show you the necessary steps to construct the rotation of a planar figure about a fixed point. You will need a compass, straightedge, and a protractor to follow along.
