Stake attention in this memory
An open, lined notebook displays handwritten mathematical equations in black ink. On the right page, problems involving integrals and derivatives are partially solved, including expressions like "2x + ln(x) + 1/(2x^2) + G∈R" and "∫ (1+e^x)/e^x dx". A section of a solution, "∫ e^-x dx + ∫ 1 dx", is outlined in red ink. On the left page, other calculus steps are visible, and the date "24/02/26" is present at the bottom. A yellow and black striped pencil rests vertically between the notebook's pages. Above the notebook, a transparent-barreled ballpoint pen with blue ink lies horizontally, positioned next to a partially visible white rectangular eraser. A dark gray camouflage-patterned fabric pencil case, displaying a partial "EASTPAK" logo, is located in the upper left corner of the frame. All objects are situated on a smooth, white surface, likely a desk or table, under indirect lighting which casts soft shadows to the right and bottom of the items. No people are visible. The image contains no specific visual information to identify the location as Bragança, Portugal.
