How do you determine if a function is bounded above or below?

WebIf a sequence does not converge, it is a divergent sequence, and we say the limit does not exist. We remark that the convergence or divergence of a sequence {an} depends only on what happens to the terms an as n → ∞. Therefore, if a finite number of terms b1, b2,…, bN are placed before a1 to create a new sequence b1, b2,…, bN, a1, a2,…, WebThe answer had better be \No" or our de nition is suspect.

If you integrate f (x ) to get an antiderivative, and then di erentiate the antideriva-tive, you get the original function f (x ). c. If the tangent line to the graph of a continuous function f (x ) at x = c is vertical, f (x ) is not di erentiable at x = c. d. If f (x ) is not continuous at a point x , it is not di erentiable at this point. e. Webanconverges, that means the sequence of partial sums { Pk n˘1an} is a con- vergent sequence, so by Theorem 3.2(c) it is bounded, and thus part(a)is satisﬁed. The problem with using this theorem with {bn} is that it doesn’t necessarily converge to 0. bratz bike purple
