WebThis is the limit as x approaches pi over two of sine of x over cosine of x. Now sine of pi over two is one, but cosine of pi over two is zero. So if you were to just substitute in, this would … WebLEMMA 3.1. If F:Ω → C′ is a closed valued multifunction, then the following two statements (a) and (b) are equivalent. F is the pointwise limit on Ω of a sequence of strongly …

WebJul 18, 2024 · Pointwise Convergence Consider the general sequence of functions fn (x). If for any value of x within the domain, we take the limit as n goes to infinity and we end up with some function f (x), then we say that the sequence of functions fn converges pointwise to f. For example, the sequence of functions converges pointwise to WebThe assumption that the sequence is dominated by some integrable g cannot be dispensed with. This may be seen as follows: define fn(x) = n for x in the interval (0, 1/n] and fn(x) = 0 … female genital mutilation scholarly articles
