Cosine of 51
WebWhat is the cosine? For a given angle in a right triangle, cosine is the ratio of the adjacent side to the longest side, or hypotenuse. Since the hypotenuse is longest, the adjacent side can be – at max – equal to the hypotenuse. It follows that cosine is … WebSine, Cosine and Tangent are the main functions used in Trigonometry and are based on a Right-Angled Triangle. Before getting stuck into the functions, it helps to give a name to …

WebSin and Cos of 3°, 21°, 33°, 39°, 51°, 57°, 69°, and 87° each have two answers. One is longer, but the Sqrt’s are nested only two deep; one is more concise but the Sqrt’s are three deep. A concise two-deep answer would be preferred, and other simplifications are also welcomed. Credit will be given. WebThe cosine is a trigonometric function of an angle, usually defined for acute angles within a right-angled triangle as the ratio of the length of the adjacent side to the hypotenuse. It is the complement to the sine. In the …

WebInverse cosine function. The arccosine of x is defined as the inverse cosine function of x when -1≤x≤1. When the cosine of y is equal to x: cos y = x. Then the arccosine of x is equal to the inverse cosine function of x, which is equal to y: arccos x = cos-1 x = y. Example. arccos 1 = cos-1 1 = 0 rad = 0° See: Arccos function.
