The knowledge base Ken has on this topic area was quite extensive and I could tell it comes from a lot of real world design experience. I plan to continue working with Ken, because he is patient, competent, and covers topic helping you to think analytically about how to solve problems. There is a saying that "If you give a man a fish you feed him for a day, but if you teach a man to fish you feed him for life" and I think Ken is the type of tutor that will teach you to fish.
He went over Maclaurin series and Taylor series. Also helped me to practice multiple choice and free response questions. Appreciate your help and tutoring. Thanks
2nd lesson with Elvis. Studied Taylor series, radius of conversions, Power Series. He explains things well and is able to come up with other examples to better understand the concepts. Wish we would have found him earlier in the year.
