Engineering Mathematics – Calculus ePrep Course: Sample Materials
1. Video Lesson (Area between Curves)
This video lesson discusses the determination of the area between two curves, by first finding the points of intersection, and then determine the area of the region bounded by the two curves by integrating the areas of the tiny triangles within the region. More Sample Videos.
2. Problem and Solution (Integration)
Evaluate the integral
3. Review of Algebra (Binomial Theorem)
Algebra is a very important and more fundamental branch of mathematics and it provides a useful tool for solving calculus problems. A review of algebra is therefore performed before the study of calculus.

2. Video Lesson on Corporate Finance (Sustainable Growth Model)
This video lesson illustrates that the Sustainable Growth Model is for a business that wants to maintain a target payout ratio and capital structure without issuing new equity, and it provides an estimate of the annual percentage increase in sales that can be supported.
3. Cross-Word Puzzle on Biotechnology (Principle of Genetic Transfer)
4. Worked Example on Engineering Economy (Project Evaluation)
A retrofitted space-heating system is being considered for a small office building. The system can be purchased and installed for $110,000, and it will save an estimated 300,000 kilowatt-hours (kWh) of electric power each year over a six-year period. A kilowatt-hour of electricity costs $0.10, and the company uses a MARR of 15% per year in its economic evaluations of refurbished systems. The market value of the system will be $8,000 at the end of six years, and additional annual operating and maintenance expenses are negligible. Use the PW method to determine whether this system should be installed.
To find the PW of the proposed heating system, we need to find the present equivalent of all associated cash flows.
The estimated annual savings in electrical power is worth 300,000 kWh × $0.10/kWh = $30,000 per year.
At a MARR of 15%, we get
PW(15%) = −$110,000 + $30,000 (P/A, 15%, 6) + $8,000 (P/F, 15%, 6)
= −$110,000 + $30,000(3.7845) + $8,000(0.4323)
Since PW(15%)≥ 0, we conclude that the retrofitted space-heating system should be installed.
MARR = Minimum Acceptable Rate of Return
PW = Present Worth
(P/A, 15%, 6) and (P/F, 15%, 6) are factors that can be obtained from tables, software, financial calculator, or by applying formulas.
5. Objective Question Exercise on Physics (Electric Power)
Two conductors made of the same material are connected across the same potential difference. Conductor A has twice the diameter and twice the length of conductor B. What is the ratio of the power delivered to A to the power delivered to B?
RA/RB = (ρLA/π(dA/2)2)/ (ρLB/π(dB/2)2)
= (LAdB2)/ (LBdA2) = (2LBdB2)/ (LB (2dB)2)
= 2/4 = ½.
PA/PB = (ΔV2/RA)/ (ΔV2/RB)
= RB/RA = 2.
6. Web Exercise on Psychology (Human Development)
Since having their first child, Bob and Angela notice that they no longer feel they have anything in common with their childless friends and are spending a lot more time with other parents. Psychologists would say that:
a their ingroup has changed from nonparents to parents.
b this is an example of group polarization.
c they have a stereotype about what parents are like.
d their attribution processes are now different than before.
7. Video Lesson on Mechanics (Work and Energy)
This short video explains the relationship between power, rate of work done, total work done, and time taken to perform the work.
8. Screen Record of Animation on Life Science (Translocation)
This is a screen record of animation that illustrates translocation in chromosomes.
9. Python Programming (Histogram)
import numpy as np
import matplotlib.pyplot as plt
# example data
mu = 100 # mean of distribution
sigma = 20 # standard deviation of distribution
x = mu + sigma * np.random.randn(1000) #normal dist with mu and sigma
subdivisions = 25
fig, ax = plt.subplots()
n, bins, patches = ax.hist(x, subdivisions, density=True) #histogram
y = ((1 / (np.sqrt(2 * np.pi) * sigma)) *
np.exp(-0.5 * (1 / sigma * (bins – mu))**2)) # create theoretical line
ax.plot(bins, y, ‘.’)
ax.set_title(r’Histogram: $\mu=100$, $\sigma=20$’)
fig.tight_layout() #provide spacing to prevent clipping of y-axis abel
10. Economics (The Marginal-Cost Curve and the Firm’s Supply Decision)
1. Cost curves have special features that are important for our analysis.
- The marginal cost curve is upward slopping.
- The average total cost curve is u-shaped.
- The marginal cost curve crosses the average total cost curve at the minimum of average total cost.
2. Marginal and average revenue can be shown by a horizontal line at the market price
3. To find the profit-maximizing level of output, we can follow the same rules that we discussed above.
- If marginal revenue is greater than the marginal cost, the firm can increase its profit by increasing output.
- If marginal cost is greater than marginal revenue, the firm can increase its profit by decreasing output.
- At the profit-maximizing level of output, marginal revenue is equal to marginal cost.
4. If the price in the market were to change to P2, the firm would set its new level of output by equating marginal revenue and marginal cost.
5. Because the firm’s marginal cost curve determines how much the firm is willing to supply at any price, it is the competitive firm’s supply curve.
11. Discrete Mathematics (Euclidian Algorithm)
Shown above are samples of the bonus materials on other subjects and they illustrate how comprehensive and broad-base this Engineering Mathematics – Calculus ePrep course is for preparing students for their university studies or for their career advancement. While not all the bonus course materials may be of interest to the students who take up this ePrep course on Engineering Mathematics – Calculus, they can choose which of these bonus course materials are of interest and download them and ignore the rest.
It is a gentle persuasion to NSFs not to short-change themselves wasting their precious e-PREP Credits on those low-grade courses prepared by any “Tom-Dick-And-Harry” who self-claim to be an industry expert, especially if they are proceeding to further academic studies! They do not need thousands of such courses. As you can see, with this single Engineering Mathematics – Calculus course, you get a good suite of course materials on many other subjects as well. You also get a hard copy Calculus textbook by James Stewart.
It is only wise to go for a high-quality specially-designed academic course such as this Engineering Mathematics – Calculus e_prep course for getting you a head start in university.
Who Should Take This ePrep Course
A must for all students doing engineering, computer science, and physical science degrees.
Also useful for students doing biology and other life science, statistics, economics, and business degrees. (Alternative to: Mathematics for Managerial, Life and Soc Sciences)
Even for those not going to any university due to various reasons, this is an opportunity to build up their mathematics foundation and to prove that they are capable of completing a university-level course. In this way, they too will be able to proceed to obtain a full university education as well.
Everyone is welcome and there is no pre-requisite. This course will provide the fundamentals (till very advanced materials) that you will need in studying calculus and the other branches of mathermatics!
