Charles Autterson
Trigonometry teacher | Tutor for 5 years
With a passion for Trigonometry, my journey led me to specialize in this dynamic field at Baker College. Armed with a profound understanding of angles, ratios, and functions, I'm here to guide you through the complexities of Trigonometry. Let's unravel the mysteries together, turning challenges into triumphs. Your success is my mission.
