Web0.5 The distance between your vectors depends on the vector space and therefor on the features you use to calculate the vectors. Given the definition you mentioned (0= no similarity, 1=identical), a similarity above 0.5 might be a good starting point. How do you calculate similarity? In the equation, A and B are data objects represented by vectors. WebWe know. The angle the cable makes with the seabed is 39°. The cable's length is 30 m. And we want to know "d" (the distance down). Start with: sin 39° = opposite/hypotenuse. Include lengths: sin 39° = d/30. Swap sides: d/30 = sin 39°. Use a calculator to find sin 39°: d/30 = 0.6293…. Multiply both sides by 30: d = 0.6293… x 30. WebMathematically, the cosine function formula in terms of sides of a right-angled triangle is written as: cos x = Adjacent Side/Hypotenuse = Base/Hypotenuse, where x is the acute angle between the base and the hypotenuse.
