Tan theta 2 find sin theta

Webtan (θ) = − 2 7 tan ( θ) = - 2 7. Use the definition of tangent to find the known sides of the unit circle right triangle. The quadrant determines the sign on each of the values. tan(θ) = opposite adjacent tan ( θ) = opposite adjacent. Find the hypotenuse of the unit circle triangle. Since the opposite and adjacent sides are known, use ... 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.
