2x2 grid, do this for 4 famous countries: ƒ(x) = [VARIABLE_SUBJECT] lim (x → [VARIABLE_STATE]) ƒ(x) Variables: [VARIABLE_SUBJECT] = "$country" [VARIABLE_STATE1] = "$countries's famous food" [VARIABLE_STATE2] = "$countries's 2nd famous food" [CALCULUS_EXECUTION] Render the exact threshold of the asymptote. The left side of the subject is [VARIABLE_SUBJECT] made of 100% [VARIABLE_STATE1] . The right side approaches 100% [VARIABLE_STATE2]. The transition must not be a blur, but a mathematical disintegration
