Trigonometry teacher | Experienced educator in USA

I hold a degree in Trigonometry from York College of Pennsylvania. My passion lies in unraveling the complexities of angles and triangles, guiding students towards mastery in this field. With a deep understanding of mathematical principles, I strive to make Trigonometry not just understandable but enjoyable. From basic trigonometric functions to advanced applications, I am here to demystify this subject for my students. Let's embark on this mathematical journey together, where every angle holds a new opportunity for learning and growth.
