What Is MATH 111?

MATH 111 — Pre-Calculus for Aviation — is a 3-credit course required for most Embry-Riddle Worldwide students pursuing degrees in Aeronautical Science, Professional Aeronautics, and Aircraft Maintenance. It’s the mathematical foundation that prepares you for MATH 112 (Applied Calculus for Aviation) and, for engineering tracks, MATH 241 (Calculus and Analytic Geometry I).

Unlike a generic pre-calculus course, MATH 111 is built around aviation applications. The textbook is Washington and Evans’ Basic Technical Mathematics with Calculus (11th edition, Pearson), which emphasizes technical and applied problem-solving. Problems involve scenarios like calculating wind correction angles, determining aircraft ground speed versus airspeed, analyzing flight paths using vectors, and solving navigation triangles with the laws of sines and cosines.

To enroll in MATH 111, you need either MATH 106 or a qualifying score on the ALEKS placement exam. Students who score lower on ALEKS typically start in MATH 106; those who score higher may place directly into MATH 111 or even MATH 140/141.

The course runs over ERAU’s standard 9-week online term. Each week you’ll complete MyMathLab homework, participate in Canvas discussions (often using the equation editor or MathType), and submit turn-in assignments for more complex problems. The midterm and final exams are cumulative and typically proctored using Respondus LockDown Browser.

Topics Covered

MATH 111 covers a wide range of pre-calculus topics, each tied back to technical and aviation applications. Here’s what you’ll encounter across the 9-week term:

Topic Area Key Concepts Aviation Application
Algebra Fundamentals Linear equations, systems of equations, inequalities Traffic flow models, fuel consumption calculations
Quadratic Equations Factoring, quadratic formula, graphing parabolas Projectile motion, rocket path analysis
Variation Direct, inverse, and joint variation Centrifugal force on turbine blades, projected image scaling
Functions Polynomial, rational, exponential, logarithmic Atmospheric pressure models, decibel calculations
Trigonometry Unit circle, radian measure, right triangle trig Angle of descent, altitude calculations
Vectors Vector addition, component form, resultant vectors Ground speed vs. airspeed, wind correction angles
Laws of Sines & Cosines Solving oblique triangles, ambiguous case Distance to station, triangulation, navigation

The aviation framing is what makes MATH 111 unique — and occasionally frustrating. You’re not just solving for x; you’re figuring out how a 30-knot crosswind affects your heading or how long it takes a submarine to descend 140 feet at a 7-degree angle of depression. The math is standard pre-calculus, but the context requires an extra layer of interpretation.

Platform and Tools

MATH 111 at ERAU Worldwide uses two main systems:

MyMathLab (Pearson)

The primary homework and testing platform. Problems are auto-graded with strict syntax requirements. MML also includes the digital textbook, help tools, and “View an Example” features. Most homework allows multiple attempts.

Canvas

Course management, announcements, discussion posts, and turn-in assignments. Canvas also hosts the proctored exams via Respondus LockDown Browser integration. You’ll use the Canvas Equation Editor for many discussion posts.

MathType / Equation Editor

ERAU provides MathType by Design Science for writing equations in Word documents. You can also use the Canvas Equation Editor for discussion posts. Getting comfortable with one of these tools is essential for turn-in assignments.

Scientific Calculator

A calculator with SIN, COS, and TAN functions is required. Graphing calculators (TI-83, TI-84) are recommended but not mandatory. You’ll need to be comfortable with radian/degree mode switching and inverse trig functions.

Homework assignments live in MyMathLab and are due weekly. The platform provides help on each problem, but its syntax requirements are notoriously strict — a missing parenthesis or incorrect rounding can cost you points even when your math is right. That’s where we come in.

Why MATH 111 Is Harder Than It Looks

On paper, MATH 111 is “just pre-calculus.” But several factors make it more challenging than students expect:

The 9-Week Compression

A typical 16-week pre-calculus course gets squeezed into 9 weeks. That means covering algebra, trig, vectors, and the laws of sines/cosines at nearly double speed. Fall behind one week and you’re playing catch-up for the rest of the term.

Aviation Context Adds Interpretation

You’re not just solving equations — you’re interpreting them in aviation scenarios. “A submarine descends at 7° at 9 mph” requires you to draw the right triangle, identify which trig function applies, and set up the equation correctly before you even start computing.

Vectors Are a Conceptual Leap

Many students haven’t worked with vectors before. Breaking a velocity into horizontal and vertical components, adding wind vectors to heading vectors, and finding resultant magnitudes and directions is genuinely new material — not just a review of high school math.

MyMathLab’s Syntax Strictness

The platform is unforgiving. Enter 3.14 instead of π? Wrong. Forget parentheses around a denominator? Wrong. Round to 2 decimals when it wanted 3? Wrong. Correct math with incorrect formatting still costs you points.

Proctored Exams With Respondus

The midterm and final are typically proctored using Respondus LockDown Browser. You can’t open other tabs, can’t use online calculators, and the webcam is watching. The pressure is real, especially if you’ve relied on outside resources for homework.

How FMMC Helps

We handle every component of MATH 111, from weekly homework to the final exam. Here’s how we support you:

1

MyMathLab Homework

We complete your weekly MyMathLab assignments with correct answers and proper formatting. We know the platform’s syntax quirks — exact values vs. decimals, parentheses placement, radian vs. degree mode — and get it right the first time.

2

Canvas Discussions

Discussion posts in MATH 111 often involve solving personalized “PIN problems” — word problems that use digits from your student ID. We solve your specific problem, format the math using the Canvas Equation Editor, and write up the explanation so you can post it.

3

Turn-In Assignments

Some modules include Word document turn-in assignments — traffic flow problems, rocket path analysis, oblique triangle navigation. We complete these with proper MathType formatting, clear step-by-step solutions, and professional presentation.

4

Midterm & Final Exams

The cumulative exams are typically proctored with Respondus LockDown Browser. We can help you prepare, or — depending on your proctoring setup — assist during the exam itself. Contact us to discuss what’s possible for your specific situation.
