The image shows a handmade trigonometric table displaying values for sine, cosine, and tangent at angles of 0°, 30°, 45°, 60°, and 90°. The table is written in pink marker on a white poster board, with grid lines also in pink. The top row lists the angles with degree symbols. The leftmost column lists "sin α", "cos α", and "tan α". The values for sine are $\frac{\sqrt{0}}{2}=0$, $\frac{\sqrt{1}}{2}=\frac{1}{2}$, $\frac{\sqrt{2}}{2}$, $\frac{\sqrt{3}}{2}$, and $\frac{\sqrt{4}}{2}=1$. The values for cosine are 1, $\frac{\sqrt{3}}{2}$, $\frac{\sqrt{2}}{2}$, $\frac{1}{2}$, and 0. The values for tangent are 0, $\frac{1}{\sqrt{3}}$, 1, $\sqrt{3}$, and undefined (represented by a dash). The poster is decorated with small pink and silver hearts along the right edge. A white ribbon bow is tied at the bottom right corner. In the top left corner, handwritten text in pink reads "Виктория Александрова 9А". The poster is partially unfurled and supported by a dark chair, with a wooden floor visible beneath. The background appears to be a light pink upholstered surface, likely a chair or sofa. There are no discernible landmarks or contextual clues to place this image within the city of Varna, Bulgaria. The scene appears to be an indoor setting. in Varna, Bulgaria
