This image displays an open, lined exercise book filled with handwritten mathematical equations in blue ink, centered on a light-colored surface, likely a desk or table. The text visible on the left page references "Lagrange Interpolation formula" and includes algebraic expressions with terms like "(x-0)(x-3)(x-4)". The right page continues with more complex calculations involving fractions and numerical values, demonstrating the application of the Lagrange Interpolation method, culminating in the expression "f(x) = 330". A partially visible plastic water bottle with a blue cap and a white spiral-bound notebook are present in the upper right background. No individuals are visible, and no actions are depicted beyond the static arrangement of study materials. The image does not contain any visual information to confirm the specific location within the city of Jos, Nigeria.
