The image captures a classroom scene in Sofia, Bulgaria, from a student's viewpoint. A female teacher, with dark hair in a ponytail, wearing a grey turtleneck, a grey open cardigan, and a floral patterned skirt, stands to the right of a whiteboard, facing the seated students. She holds a small, rectangular metallic object in her right hand. The whiteboard is filled with handwritten Bulgarian text and mathematical equations related to trigonometry. Prominently displayed is the date "25.03.26г" (March 25, 2026) and the title "Основни тригонометрични тъждества" (Basic trigonometric identities). Equations such as sin²α + cos²α = 1, tgα cotgα = 1, and various trigonometric identities involving angles like (180+α) and (270+α) are visible, along with a diagram of a unit circle and coordinate points. In the immediate foreground, the back of a female student's head with long, straight dark brown hair is visible on the left, and the back of a male student's head with short dark hair, wearing a white shirt, is visible on the right. A clear plastic water bottle with a blue cap is positioned on a desk surface between these two foreground students. Additional students are partially obscured in the mid-ground. The setting indicates an active mathematics lesson.
