Precalculus 4: Exponentials and logarithms — Udemy Coupon 93% 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 concerning exponentials or logarithms (illustrated with 239 solved problems) and why these methods work.
• Applications of exponential and logarithmic functions in finance, engineering, and natural sciences (some of them in my videos, some as reading material).
• Binomial Theorem with two proofs (a combinatorial one and one by induction), Pascal's Triangle, and how to apply them.
• Definitions of Euler's number e, how to approximate it, and how to prove that this number is irrational.
• Definitions and computational rules for powers with various types of exponents (natural, integer, rational, real).
• Definition of logarithms in relation to exponents, with computational rules (these will be related to the rules for powers).
• Exponential functions, their properties and graphs.
• Logarithmic functions, their properties and graphs.
• Power functions, their properties and graphs; interactions between power functions and exponential functions.
• Graph transformations for exponential and logarithmic functions, and for some power functions.
• Solving exponential equations and inequalities.
• Solving logarithmic equations and inequalities.

Before you start

• High-school mathematics, mainly arithmetic; solving simple equations (linear and quadratic) with one unknown; some (but very few) polynomial equations will be solved during the course, but you can skip them if you want to (no problem at all; it will not affect your understanding of the main subjects of the course)
• Precalculus 1: Basic notions (mainly the concept of function and related concepts; sets; logic)
• 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 4: Exponentials and logarithms 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 3,288 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 50h

Total runtime is 50h of video, which you work through self-paced with lifetime access. The published syllabus lists 12 outcomes — headlined by how to solve problems concerning exponentials or logarithms (illustrated with 239 solved problems) and why these methods work.; applications of exponential and logarithmic functions in finance, engineering, and natural sciences (some of them in my videos, some as reading material).; binomial Theorem with two proofs (a combinatorial one and one by induction), Pascal's Triangle, and how to apply them..

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. $149.99 is the list price, but Udemy courses at this level almost never sell at list. This coupon brings it to $9.99 — a 93% cut worth $140.00. Spread over the runtime, that is about $0.20 per hour of instruction — cheaper than a coffee per study session.
