Let’s suppose that the angle between the two vectors is 90 degrees, meaning they have cosine similarity equal to 0. Geometrically, the vectors are perpendicular to each other, which indicates that these vectors do not have any relation. As the angle of the vectors decreases from 90 to 0 d...

One notable property of cosine distance is its scale invariance. This means that the cosine distance between two vectors remains the same even if you multiply either or both vectors by a scalar (non-zero constant). Mathematically, for any nonzero scalars a and b, and vectors x and y: Cos...
So cosine similarity in machine learning can be used as a metric for deciding the optimal number of neighbors where the data points with a higher similarity will be considered as the nearest neighbors and the data points with lower similarity will not be considered. So this is how cosine simil...

Sine and cosine functions are closely related and can be understood through the unit circle, where the value of sine is the y-coordinate of a point on the circle, while cosine is the x-coordinate. This relationship highlights how the two functions complement each other and are integral to un...
What is the arccos of 0 ? arccos 0 = ? The arccosine is the inverse cosine function. Since cos 0 = cos 0º = 1 The arccosine of 0 is equal to the inverse cosine function of 0, which is equal to π/2 radians or 90 degrees: arccos 0 = cos-1 0 = π/2 rad = 90º See...
