SUMMARY
The discussion centers on the application of trigonometric functions in physics, specifically regarding tangential and radial acceleration. The user seeks clarification on why cosine is used for the tangential component of acceleration and sine for the radial component. The fundamental principle is based on the definitions of sine and cosine in relation to right triangles, where cosine represents the adjacent side over the hypotenuse, and sine represents the opposite side over the hypotenuse, as outlined by the mnemonic SOHCAHTOA.
