Description

This study identifies a global challenge in mathematics and physics education: a widespread "blind spot" of trigonometric derivatives and their implications for physical systems. Data were collected from 700 university science students across four countries: Israel, USA, China, and India. Findings show that 70%-80% of participants were unaware that these derivatives differ when measured in degrees versus radians, highlighting a systematic gap. In the context of harmonic oscillation, incorrect responses dropped to 35-45%, yet many still struggled to explain why radians are necessary. The consistent results across countries emphasize the need for targeted pedagogical strategies to address this issue.
