Instead of approximating ln x near x = 1, we approximate ln (1 + x) near x
Question:
Instead of approximating ln x near x = 1, we approximate ln (1 + x) near x = 0. We get a simpler formula this way.
a. Derive the linearization ln (1 + x) ≈ x at x = 0.
b. Estimate to five decimal places the error involved in replacing ln (1 + x) by x on the interval 30, 0.14 .
c. Graph ln (1 + x) and x together for 0 ≤ x ≤ 0.5. Use different colors, if available. At what points does the approximation of ln (1 + x) seem best? Least good? By reading coordinates from the graphs, find as good an upper bound for the error as your grapher will allow.

I graduated from Maseno University with a Bachelor of Science in Applied Statistics. After graduation, I started tutoring students in mathematics. My experience in mathematics education is extensive and varied. I have taught a wide range of topics, including algebra, geometry, trigonometry, calculus, statistics, probability, and computer science. I have also worked with students of all ages and backgrounds, from elementary school to college.
My teaching method is based on the idea of hands-on learning. I believe that students learn best when they are actively engaged in the learning process, so I focus on giving students the tools they need to explore the material on their own. I also emphasize the importance of practice and review, as these are essential for mastering math concepts.
I have also developed several online and in-person courses on mathematics. My courses are designed to help students learn mathematics in an efficient and comprehensive way, and I use a variety of activities and exercises to ensure that my students are engaged and motivated.
Overall, my passion for mathematics and teaching has allowed me to be a successful tutor and educator in the field. I am confident that my experience will help your students master the mathematics they need to succeed.
