About Ethan
Hello, I am Dr. Ethan Tsai. I am a professional mathematician with a Ph.D. degree and a passion for teaching. I specialize in visualizing complex concepts to make Calculus accessible to everyone. I have authored a series of Calculus textbooks available on Amazon and created a comprehensive online curriculum used by students worldwide. With my bilingual background (English/Mandarin), I bridge the gap between abstract math theory and practical problem-solving skills.

I specialize in breaking down complex Calculus concepts into visual, easy-to-understand logic. My teaching is based on my background as a Ph.D. in Mathematics and an Amazon textbook author.
Unlike traditional lectures that rely on rote memorization, I use a unique 'Knowledge Map' method to take you from confusion to clarity.
My lessons are supported by my own structured learning materials, including the 'Master Calculus with Ease' video series and fill-in-the-blank notes. Whether you need help with Limits, Derivatives, or Integrals, I will help you master the 'why' behind every formula.
