Precalculus 1: Basic notions — Udemy Coupon 94% OFF

Quick Verdict: Is This Math Coupon Worth It?

What You'll Learn

Practical takeaways waiting inside this Teaching & Academics course:

• How to solve problems in chosen Precalculus topics (illustrated with 236 solved problems) and why these methods work.
• Repetition of chosen aspects of high school mathematics (basic notions as numbers, functions, sets, equations, and inequalities).
• The basic notions will be defined in a more abstract way, and you will get an insight into their place in Calculus and some other branches of university maths.
• By the end of this course you will be able to understand all the elements in the epsilon-delta definition of limit, both symbols and the content.
• Arithmetic with basic rules (associativity and commutativity of addition and multiplication, distributivity) illustrated for positive integers.
• Basic terminology for equations and inequalities, with examples of linear equations and inequalities, with and without absolute value.
• Basic concepts related to functions (domain, range, graph, surjection, injection, bijection, inverse, composition) and how to work with them.
• Functions: monotone (increasing, decreasing), bounded, even, odd; extremum: maximum, minimum, both local and global.
• Geometrical operations on graphs of functions: translations, reflections, shrinking, dilating. Piecewise functions.
• Absolute value and its role in computing distances, with geometrical illustrations and functional approach.
• Equations of straight lines in the plane: slope and intercept; first glimpse into derivative as the slope of the tangent line, and link to monotonicity.
• Introduction to sequences and series; short notation for sum (Sigma) and product (Pi); arithmetic, geometric, and harmonic progressions.
• Logic: symbols and rules (tautologies) used for creating mathematical statements, definitions, and proofs.
• Set theory: union, intersection, complement, set difference; some important rules and notation.
• Relations: RST (equivalence) relations, order relations, functions as relations.
• Necessary and sufficient conditions: definition and examples.
• Various types of proofs: direct, indirect, by contradiction, induction proof, with some examples.
• Building blocks of mathematical theories: axioms, definitions, theorems, propositions, lemmas, corollaries, etc.
• Decimal expansion of rational and irrational numbers. Density of Q and R\Q in R.
• Cardinality of sets: finite sets, N, Z, Q, R; countable and uncountable sets.
• You will also get a solid background for any future studies in Real Analysis and other courses in university mathematics.

Before you start

• Basic high school mathematics (mainly arithmetic)
• You are always welcome with your questions. If something in the lectures is unclear, please, ask. It is best to use QA, so that all the other students can see my additional explanations about the unclear topics. Remember: you are never alone with your doubts, and it is to everybody's advantage if you ask your questions on the forum.

Is Precalculus 1: Basic notions Still Relevant?

The last update landed September 12, 2026 — and for a Teaching & Academics course, freshness is the first thing to verify. An updated date means the instructor still maintains the material; a stale one means you learn last year's version of the tools.

The 4.9 rating from 8,614 learners suggests the content holds up in practice — ratings at that level rarely survive contact with outdated material. The entry bar looks low, which makes this a reasonable first course in the topic rather than a capstone.

What the Course Actually Delivers in 52h 30m

The published syllabus lists 21 outcomes — headlined by how to solve problems in chosen Precalculus topics (illustrated with 236 solved problems) and why these methods work.; repetition of chosen aspects of high school mathematics (basic notions as numbers, functions, sets, equations, and inequalities).; the basic notions will be defined in a more abstract way, and you will get an insight into their place in Calculus and some other branches of university maths.. Total runtime is 52h 30m of video, which you work through self-paced with lifetime access.

Is the Price Fair After the Coupon Discount?

The real comparison is not list versus coupon, but coupon versus the next-best course at the same sale price — and on ratings-per-dollar, this one compares well. $174.99 is the list price, but Udemy courses at this level almost never sell at list. This coupon brings it to $9.99 — a 94% cut worth $165.00. Spread over the runtime, that is about $0.19 per hour of instruction — cheaper than a coffee per study session.
