Mr. A's Math Podcast
10 episodes - English - Latest episode: over 8 years ago - ★★★★★ - 1 ratingI'm a High School math teacher, and huge math nerd. I'm creating this podcast to share math that I find interesting, as well as create a space where I can help people with the mathematics they learn in High School; Geometry, Algebra II/Trig, and Calculus. If you have a question, send me an email- and I'll try to put up a video for you. If you enjoy the podcast please subscribe, and look for me on Youtube at: https://www.youtube.com/mikedobbs76

Calc – Optimization II
December 06, 2015 22:26 VideoIn 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. If you enjoy […]
Calc – Optimization I
December 06, 2015 22:23 VideoIn 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. If you enjoy this video please like, subscribe and comment. Also, check out my podcast on […]
Working With Isosceles Triangle Theorems in Proof
December 01, 2015 21:56 VideoIsosceles 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 […]
Curve Sketching
November 20, 2015 13:52 VideoAn 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. If you enjoy this video please like, subscribe and comment. Also, check […]
Working with Linear Pairs in a Two-Column Proof
November 17, 2015 21:05 VideoThis 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. If you enjoy this video please like, subscribe and comment. Also, […]
Construction: Dilation by a scale factor of 5/3
April 10, 2015 21:25 VideoIn 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: Dilation by a scale factor of 3/7
April 02, 2015 22:36 VideoIn this video I take you through the construction of a dilation in the plane with a scale factor of 3/7. You will need a compass and straightedge to follow along. If you enjoy this video please like, subscribe and comment. Also, check out my math raps on YouTube
Construction: Dividing a segment into a given ratio
March 30, 2015 22:38 VideoIn 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. Dividing a segment into a given […]
Construction: Dilation in the plane from an external point
March 24, 2015 22:56In 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 […]
Construction: Rotation about a fixed point
March 22, 2015 03:10 VideoIn 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. Constructing a rotation about a fixed point
