Profile

I am a graduate of Cleveland State University. After earning my Bachelors of Electrical Engineering I went on to earn a Master’s of Science in Electrical Engineering. Also I am a graduate of Lorain County Community College (LCCC) earning an Associates of Science Pre-Professional Engineering and an Associates of Applied Science Electronic Engineering Technology. Presently I am a Math Tutor at LCCC tutoring basic math courses, Technical Mathematics 1 and 2, Advance Technical Calculus, Business Calculus, Statistics, College Algebra, Pre-Calculus, Trigonometry and Calculus 1 and 2. I have taught Calculus 1 and 2, Multivariable Calculus Pre-Calculus, College Algebra, Statistics, Technical Mathematics 1 and 2, Advance Technical Calculus, Finite Mathematics, Electric Circuits 1 and 2, Electronic Devices and Digital Electronics.

As a high school student I have always found mathematics amazing and my favorite subjects are Calculus and Trigonometry. My viewpoint about teaching is that I explain the steps how to solve a variety of problems with the expectation that a student can apply these steps to not only the problems that I went over but to other problems not seen before. When tutoring students I try different solving techniques if the student does not understand the current method I am explaining. I am delighted when a student states a comment similar to “Is that it. That was easier than I thought”. In my experience what hinders a student passing a course is dislike of the subject or instructor, lack of self-confidence (a feeling that I am dumb) and not putting in enough study time. In my free time I run, cook, work on my car and play video games.

Finding the Domain of Functions

In this tutorial I will demonstrate the process of finding the domain of a function. The domain of a function is all the allowable values of real numbers that the independent variable (usually x) can be. The restrictions (what we cannot do with real numbers) are 1) Can’t divide by zero. 2) Can’have a negative…

Solving Trigonometric Equations Part 2

This is part 2 of 2 on Solving Trigonometric Equations (see Solving Trigonometric Equations Part 1 for problems 1 to 5). In this tutorial I will solve several different trigonometric equations using different techniques such as factoring, substitution and converting the equation to all one trigonometric function using identities. Solving trigonometric equations involves knowledge of…

Minimal Volume of a Cone Circumscribed about a Sphere

Find the minimal volume and dimensions of a right circular cone circumscribed about a sphere of a given volume. To solve this problem we need to know 1) The formula for the volume of a sphere V = \frac{4 {\pi} r^{2}}{3} 2) The formula for the volume of a cone $V = \frac{{\pi} r^{2} h}…

Standard Deviation and Standard Error

As a math and statistic tutor I have often been asked “What is the difference between standard deviation and standard error?” My objective in this tutorial is to demonstrate with an example what the difference is. To fully comprehend the difference we need to know what a sampling distribution is and the definitions of standard…
