A value between -1 and 1. A domain error will occur if x is not between -1 and 1.ReturnsThe acos function returns the arc cosine of a number represented by x. It will return a value between 0 and π.Required HeaderIn the C Language, the required header for the acos function is:#...
1.(Mathematics) Also called:circular functionany of a group of functions of an angle expressed as a ratio of two of the sides of a right-angled triangle containing the angle. The group includes sine, cosine, tangent, secant, cosecant, and cotangent ...
Cosine rule, in trigonometry, is used to find the sides and angles of a triangle. Cosine rule is also called law of cosine. This law says c^2 = a^2 + b^2 − 2ab cos(C). Learn to prove the rule with examples at BYJU’S.

5.2 Reduction of RVs It is essential that the total number of RVs present in the formulation needs to be reduced as soon as practicable. Haldar and Mahadevan (2000a, b) suggested that the information on the sensitivity indexes of RVs can be used for this purpose. They showed that the sens...
Rapidly increasing number of web pages or documents leads to topic specific filtering in order to find web pages or documents efficiently. This is a preliminary research that uses cosine similarity to implement text relevance in order to find topic specific document. This research is divided into ...
For the hyper-parameters of one-stage distillation in (10), \(\lambda _n\) and \(\lambda _p\) are set to 1, and \(\lambda _h\) is set to 1/h, where h represents the number of head layers. For two-stage distillation, the hyper-parameters \(\lambda _n\), \(\lambda _p\...
It can help you find the length of a side of a right triangle as long as you have an angle θθ and some info on the other sides of the triangle. Example problems In this chapter, we're actually going to focus on the cosine rule. This means we'll only be working with the "Cah...
Similarity measures based on the generalized distance of neutrosophic Z-number sets and their multi-attribute decision making method Although a single-valued neutrosophic set is described by the truth, indeterminacy and falsity membership degrees, it lacks the reliability measures of the ...
