Cosine of 58
WebArccos. Arccosine, written as arccos or cos-1 (not to be confused with ), is the inverse cosine function. Cosine only has an inverse on a restricted domain, 0≤x≤π. In the figure below, the portion of the graph highlighted in red shows the portion of the graph of cos (x) that has an inverse. The domain must be restricted because in order ... WebThe Sine function ( sin (x) ) The sine 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 opposite side to the longest side of the triangle. In the illustration below, sin (α) = a/c and sin (β) = b/c. From cos (α) = a/c follows that the sine of any angle ...
