Testimonial

I am extremely indebted to Dr. David Campbell.
David, not only helped my daughter Jacquelyne Khan but he is presently helping my son with math and physics. When my daughter was in high school, she was really struggling with her grade 12 math and physics. She was on the verge of dropping out of school.

However, I was extremely lucky to meet David Campbell. With his considerate and compassionate tutoring style, David was able to reach the inner strings of my daughter’s intellect. My daughter started to understand her math and physics. This understanding of math and physics spilled over to her chemistry and calculus and she started doing well in these two subjects also.

Prior to asking David Campbell for help, my daughter was helped by two other tutors but unfortunately they were not able to bring any change in her understanding of these two subjects.

I am proud to say that because of David Campbell’s help my daughter is presently attending the University of Alberta and attempting Bachelor of Science/Bachelor of education degrees. Presently David is helping my daughter with her University statistics and probability courses.
Furthermore, not only has David helped my daughter but he was very instrumental in guiding my son Christopher Khan from grade 10 to his present grade 12. In juxtaposition with my daughter, my son needed more help. He was totally incapable of understanding high school math and physics. However, Mr. David Campbell once again came to our rescue. On many occasions, he has helped my son on a one on one basis and surprisingly my son ended with a 96% average in math 20 pure. Presently he is sitting with a 80% average in math 30 pure and with a 85% in physics. Considering that when my son started high school I had no hope for his success. Now I have high hopes for his future.

David has got a gift of reaching deep into any kid’s intelligence and drawing out their capabilities. May the Lord bless Dr. David Campbell.

All this was made possible by the expertise, compassion, consideration, kindness and generosity of Mr. David Campbell. Not only my kids but I personally am very, very grateful to David for his help.

Mathematicians, especially those pursuing pure mathematics, prefer to work with exact numbers such as π , √2 , 5/7 . In the practical settings of measurement and computation, there is a need to approximate the actual value of a number, especially when a long or infinite decimal is involved. In order for such approximations to Read more about Accuracy of Approximate Numbers[…]

Here we consider a number of theorems concerned with the Euclidean geometry of the circle. We begin by reviewing some important structures related to the circle. Further Circle Anatomy The vital description of the circle in terms of its radius and centre may be found in The Shape of Things. The arc, a sometimes underestimated Read more about Classical Geometry: Part 3[…]

Here we continue the treatment of continuous probability functions (distributions) begun in Probability Functions: Part 2 and Continuous distributions. Our emphasis is on distributions derived from the normal distribution. We begin with the Chi-square distribution, which was already considered in Further Continuous Distributions. But here we approach it as a sampling distribution. We then consider Read more about Further Continuous Distributions: Part 2[…]

This is an introduction to the probability functions of continuous random variables, from a post-secondary perspective. One of the most fundamental functions of this type is the normal distribution. Since it has been covered elsewhere, our main focus is on another fundamental continuous probability function, the uniform distribution. We close this essay by considering one of Read more about Continuous Distributions[…]

Let be a power series representation of f(x) within the interval of convergence |x| < r. That is, f(x) = It is easy to show that f(0) = a0. And, since f ‘(x) = , it follows that: and f ”(x) = Then it is easy to see that f ”(0) = 2a2 Read more about McLaurin’s Series[…]

As described in Statistics Defined, a sample is a set of raw data values drawn from a much larger source, the population. Purpose is …. Before drawing a sample, an investigator should clearly define the population from which it is to come.

Our goal in this section is to illustrate how the TI-84 calculator can be used to perform tests on categorical data. Although the TI-84 is used in secondary schools, this topic is not normally covered at the secondary level in Canada. Example 1, genetic ratios (one-way table)…chi2cdf(0, chic, df) = .95 or .99 A more Read more about Categorical data and the TI-84 Calculator[…]
