Learn how to use sine, cosine, and tangent to solve real-world problems … WebThe CAST diagram tells us the quadrants for which various trigonometric functions are positive. To use this diagram, we first need to write c s c ( − 2 2 5) ∘, in terms of sine and cosine. We recall the following reciprocal trigonometric identity: c s c s i n 𝜃 ≡ 1 𝜃; therefore, c s c s i n ( − 2 2 5) = 1 ( − 2 2 5). ∘ ∘.
WebTrigonometry (from Ancient Greek τρίγωνον (trígōnon) 'triangle', and μέτρον (métron) 'measure') is a branch of mathematics concerned with relationships between angles and ratios of lengths.
