WebTrigonometry (from Ancient Greek τρίγωνον (trígōnon) 'triangle', and μέτρον (métron) 'measure') is a branch of mathematics concerned with relationships between angles and … Webtangent: cosecant: secant: cotangent: The terms used to describe the sides of a right triangle are the hypotenuse, the adjacent side, and the opposite side, as shown in the figure above. Adjacent: the side next to θ that is not the hypotenuse Opposite: the side opposite θ. Hypotenuse: the longest side of the triangle opposite the right angle.

WebThe arctangent of x is defined as the inverse tangent function of x when x is real (x ∈ℝ). When the tangent of y is equal to x: tan y = x. Then the arctangent of x is equal to the inverse tangent function of x, which is equal to y: arctan x= tan-1 x = y. Example. arctan 1 = tan-1 1 = π/4 rad = 45° Graph of arctan. Arctan rules Webtan(−t) = −tan(t) Notice in particular that sine and tangent are odd functions , being symmetric about the origin, while cosine is an even function , being symmetric about the y … WebConventionally, an abbreviation of each trigonometric function's name is used as its symbol in formulas.
