Notice how a "co-(something)" trig ratio is always the reciprocal of some "non-co" ratio. You can use this fact to help you keep straight that cosecant goes with sine and secant goes with cosine. The following (particularly the first of the three below) are called "Pythagorean" identit...

What a Nerd! Beating Students and Vector Cosine in the ESL and TOEFL Datasets In this paper, we claim that Vector Cosine, which is generally considered one of the most efficient unsupervised measures for identifying word similarity in Vector Space Models, can be outperformed by a completely unsup...
The sine is defined as it is the trigonometric function which is equal to the ratio of length of opposite side to the length of the hypotenuse. Similarly, the cosine is defined as it is the trigonometric function which is equal to ratio of the length of the adjacent side to the lengt...
Geometry is a branch of mathematics that deals with shapes and their properties. Triangles are one of the most commonly used shapes in geometry, and there are three main types of triangles: equilateral, isosceles, and scalene. In this blog post, we'll co
Hence, the cosine of 270 degrees is 0. For tangent of 270 degrees: We are well aware of the identity that $\tan \theta =\dfrac{\sin \theta }{\cos \theta }$ Thus, we can write $\tan {{270}^{\circ }}=\dfrac{\sin {{270}^{\circ }}}{\cos {{270}^{\circ }}...
Cosinesimilarity is a measure of similarity between two data points in a plane. Cosine similarity is used as a metric in different machine learning algorithms like theKNNfor determining the distance between the neighbors, in recommendation systems, it is used to recommend movies with the same simil...
