WebTrigonometry. Trigonometry (from Ancient Greek τρίγωνον (trígōnon) 'triangle', and μέτρον (métron) 'measure') is a branch of mathematics concerned with relationships between angles and ratios of lengths. The field emerged in the Hellenistic world during the 3rd century BC from applications of geometry to astronomical studies. WebJun 26, 2015 · Simply put: Because a radian is defined as the unit of measurement that makes sin(dx) ≈ dx. As you have realized, for any unit of measurement you define as the basis of sin, you'll have sin(dx) ≈ α dx for some α. There is a specific unit of measurement for which α = 1. Call this unit a radian, and you're done.

WebNow here's the thing: you're told to find the derivative of $\sin(\theta)$ when $\theta$ is in degrees. At a first glance, this seems simple: it should just be $\cos(\theta)$. However, this answer is wrong, because you found that $\sin(\theta)$ has derivative $\cos(\theta)$ under the assumption that $\theta$ is measured in radians, and not in ...
