Use the alternating series estimation theorem to determine how many terms should be used to estimate the sum of the entire series with an error of less than 0.001 or more terms should be used to estimate the sum of the entire series with an error of less than 0.001.

In single variable calculus for $f (x)$ to be continuous at $x_{0}$ we need to have $lim_{h \to 0} f (x_{0} - h) = lim_{h \to 0} f (x_{0} + h) = lim_{h \to 0} f (x_{0})$ and it should be well defined at that point.

Prove the inequality $\frac{a}{1 + a^{2}} + \frac{b}{1 + b^{2}} + \frac{c}{1 + c^{2}} \leq \frac{3 \sqrt{3}}{4}$
$a, b, c$ are nonnegative real numbers such that $a^{2} + b^{2} + c^{2} = 1$
Prove the inequality
$\frac{a}{1 + a^{2}} + \frac{b}{1 + b^{2}} + \frac{c}{1 + c^{2}} \leq \frac{3 \sqrt{3}}{4}$
I tried the method of Lagrange multipliers and Jensen's inequality but I have not been proved this inequality

Getting your pre Algebra solved becomes much easier when you have all the answers to your questions by taking a closer look at the various examples dealing with Pre-Algebra subjects. We have intentionally collected the list of pre-algebra equations and various solving equations with decimals problems to help you see various examples that explain how certain solutions are found. Still, if something sounds unclear or you are concerned about some solution that has been provided, approach pre-algebra with reverse engineering approach (going backwards).
