Trigonometry teacher | Verified Expert

With a specialization in Trigonometry from Franklin W. Olin College of Engineering, my passion lies in unraveling the complexities of angles and triangles. I believe in making mathematics not just understandable but enjoyable for my students. Guiding them through the intricacies of trigonometric functions, I foster a deep understanding that extends beyond textbooks. My goal is to ignite curiosity and empower students to approach problems with confidence. Let's explore the world of triangles together, where every angle holds a story waiting to be discovered.
