How to succeed in NJIT Math 222

Prof. Roy Goodman

The most important thing: preparation 🏃

Make sure you know calculus. If you were placed in this class but don’t know calculus well, it will be very hard.

In particular:
- Know the difference between derivatives and integrals
- Know integrals and derivatives of common functions: \(\sin{x}\), \(e^{ax}\), \(\ln x\), etc.
- Know techniques including integration by parts and \(u\)-substitution.
Calculus review materials in .

The other important thing: work 👷

There is a lot to learn! Don’t fall behind!

Start working in week one. 📆
Keep up day to day (or at least week to week). Friday’s lecture will be easier to follow if you have understood Thursday’s lecture.
Attending every lecture but doing no work is a poor strategy.
Read the book 📖, work through the examples, and try to understand the ideas. Then do the homework.
Spend 2-3 hours working for every hour of lecture.

Your time is valuable 🕰️ = 💵

Too many students take this class two or more times before passing. Put in enough time and work to pass it on the first attempt.

Our time is valuable ⏲️ = 💰

Your instructors put a lot of time into planning and teaching the class. We like to see positive results.

Read the syllabus

Understand the grading scheme

Component	Contribution
WileyPlus Homework	10%
Quizzes	10%
MATLAB Assignments	16%
Common Midterm Exam I	17%
Common Midterm Exam II	17%
Final Exam	30%

Nothing is optional. Skipping the MATLAB drops you two 2️⃣ letter grades.
Homework and quizzes are there to encourage you to keep up every week.
The homework is (relatively) easy. It can compensate (somewhat) for poor test performance.

Why so much MATLAB?

MATLAB (and computing more generally) is a tool to help visualize the solutions to differntial equations, which helps you think about the meaning of solutions and not simply write down formulas.
Numerical methods (e.g. Euler’s method, sec. 2.7) are an essential tool for understanding ODE. It helps understanding if you work with the computer code.
You will use MATLAB in later courses.
When you see ODE after this semester, numerical solutions are likely to play an important role.

For math/MATLAB help

Professor’s office hour is your first option. We like helping, especially early. 🧑‍🏫
Ask questions in class. ❓
If you don’t understand why we cover something, ask. It’s all there for a reason.

For errors in materials 😕

Contact the coordinator! There are dozens of links, assignments, and due dates in Canvas. There are bound to be mistakes. Help me fix them .

We want you to succeed!

Good luck this semester! 😄

Math

In-line math: \(x + y = z\)

Block math:

\[ f\left( x \right) = \;\frac{{2\left( {x + 4} \right)\left( {x - 4} \right)}}{{\left( {x + 4} \right)\left( {x + 1} \right)}} \]

Fragments

Make content appear incrementally

{{% fragment %}} One {{% /fragment %}}
{{% fragment %}} **Two** {{% /fragment %}}
{{% fragment %}} Three {{% /fragment %}}

Press Space to play!

One Two Three

A fragment can accept two optional parameters:

class: use a custom style (requires definition in custom CSS)
weight: sets the order in which a fragment appears

Speaker Notes

Add speaker notes to your presentation

{{% speaker_note %}}
- Only the speaker can read these notes
- Press `S` key to view

Custom CSS Example

Let’s make headers navy colored.

Create assets/css/reveal_custom.css with:

.reveal section h1,
.reveal section h2,
.reveal section h3 {
 color: navy;
}
