WebThere is continuously increasing interest in research on multi-sensor data fusion technology. Because Dempster’s rule of combination can be problematic when dealing with conflicting data, there are numerous issues that make data fusion a challenging task, including the exponential explosion, Zadeh Paradox, and one-vote veto. These issues lead to a great … WebWe know that the domain of the cosine function is R, that is, all real numbers and its range is [-1, 1]. A function f(x) has an inverse if and only if it is bijective(one-one and onto). Since cos x is not a bijective function as it is not one-one, the inverse cosine cannot have R as its range.Hence, we need to make the cosine function one-one by restricting its domain. cherry bowl pro shop
