Precalculus teacher | Experienced educator in USA

I specialize in Precalculus, guiding students through the complexities of functions, trigonometry, and more. My passion for mathematics was nurtured during my studies at the University of California College of Law, San Francisco. I believe in fostering a supportive learning environment where students feel empowered to tackle challenges and cultivate a deeper understanding of mathematical concepts. With a commitment to excellence and a personalized approach to teaching, I strive to help students unlock their full potential in the realm of mathematics. Let's embark on this mathematical journey together!
