WebQuestion Express the ratios cosA, tanA and secA in terms of sinA. Medium Solution Verified by Toppr cosA= 1−sin 2A→(1) as, cos 2θ+sin 2θ=1 tanA= cosAsinA = 1−sin 2AsinA ( from (1) ) & secA= cosA1 = 1−sin 2A1 ( From (1) ) so, cosA= 1−sin 2A,tanA= 1−sin … 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.

WebSep 15, 2024 · Example 1.7. Find the values of all six trigonometric functions of \(60^\circ \). Solution: Since we may use any right triangle which has \(60^\circ \) as one of the angles, we will use a simple one: take a triangle whose sides are all \(2 \) units long and divide it in half by drawing the bisector from one vertex to the opposite side, as in the figure on the … WebApr 23, 2024 · Express the trigonometric ratios sinA, SecA and tanA in terms of cotA - 3409501.
