About the Authors
Cameron Butler
I am Cameron Butler, an undergrad here at USC. I worked along-side with Dr. Wei-Kai
Lai to create: Proofs of a Trigonometric Inequality, a math article written to show
proof of the inequality (See article for proof) . My motivation for this proof came
from numerous reasons, beginning with my personal desire for solving difficult tasks.
I also crave the chance to use my problem solving skills, especially when it requires
abstract thinking. When the opportunity to work with Dr. Lai arises during a SC STEPs
to STEM Summer Internship Program over the summer of 2013, I quickly accepted. Since
working on this project, I have been enlightened to the importance of teamwork and
research. It also encouraged me to pursue a career that uses math and problem solving
skills. Before participating in this proof, I started my first year of college at
USC Salkehatchie Walterboro campus,which was conveniently located in my hometown.
There, I received the Dean’s Honors List for the 2012-2013 academic year, and met
Dr. Wei-Kai Lai. I now study as a sophomore at USC Columbia. I major in Civil Engineering
and wish on working toward a Master degree in the field. Though, in light of opening
my own engineering firm, I want to expand my education into business and receive a
MBA as well. I would like to thank Dr. Wei-Kai Lai. He has been an inspiring, genuine,
and caring mentor. Not enough words could express the value I have found in his ability
to share his own knowledge and wisdom. It has truly been a pleasure to work on such
an intriguing proof with the help and support of such a magnificent mind.
