This course covers: 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). . See the full curriculum on the Udemy course page for a complete breakdown.

Q: Do I need any prior knowledge to take this course?

The instructor recommends: 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.

Is the Precalculus 4: Exponentials and logarithms Coupon Worth It?

Expert review by Josh Smith, Lead Course Reviewer at CourseSpeakUpdated Aug 27, 2026

The short answer is yes — provided the Teaching & Academics skills this course teaches actually line up with what you want to build. The regular price for Precalculus 4: Exponentials and logarithms on Udemy is $149.99. The coupon code listed on this page drops that to $9.99 — a saving of $140.00, or 93% off the standard rate. Spread across 50h of on-demand video, that works out to roughly $0.20 per hour of content — less than the cost of a single chapter of most printed teaching & academics textbooks.

A discount is only worth something if the material delivers, and the curriculum here is built around practical outcomes. Hania Uscka-Wehlou walks you through 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)., and binomial Theorem with two proofs (a combinatorial one and one by induction), Pascal's Triangle, and how to apply them. — concrete skills you can apply, not abstract theory. It has already been taken by 3,259 students and holds a 4.9-star average from verified reviews, which is a reasonable sign the content holds up in practice.

The bar to entry is low: 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). That makes it a realistic choice even if Teaching & Academics is unfamiliar territory. In practical terms, expect around 50h of on-demand video to work through at your own pace. The material is presented in English.

Pros

✓Verified 93% price reduction.
✓High learner satisfaction (4.9/5).
✓Trusted by 3,259 students.
✓Certificate + lifetime access.

Cons

!The coupon is time-limited — once it expires, the price tends to revert toward the standard $149.99.
!Lifetime access is tied to Udemy staying online; the platform can change its policies.
!Budget for the exercises and quizzes too — they add real time on top of the 50h of video.
