comment Solving inequalities with absolute values on both sides
@Joseph By the way, formally, the intersection between sets is never zero, but rather is said to be empty.

comment Solving inequalities with absolute values on both sides
@Joseph yes, they go by intersection. The second inequality splits, e.g. into $(2x-1) + |1-x| \ge 3$ and $-(2x-1) + |1-x| \ge 3$.

comment Evaluate the geometric series or state that it diverges.
@Mahina You compute the terms by "plugging in" the values $k=1,2,3$ into the formula in the sum: $4\left(\frac{-1}{5}\right)^{4\cdot 1}, 4\left(\frac{-1}{5}\right)^{4\cdot 2}, 4\left(\frac{-1}{5}\right)^{4\cdot 3}$. Simplify these, and then you get first term to be $a$ and ratio to be $r$. Check that ratio of 2nd/1st and 3rd/2nd terms is the same.

@Mahina Ignore? Why? Write out the first three terms, what are they?

comment Have some trouble with limits
Do you know about Taylor series? That would help a lot with (3) and (4). Factor the denominator of (2) at $a^3-b^3$ with $a = \sqrt[3]{x}, b= 1$.

comment Can a transcendental number be an infimum of a set of rationals?
@user2345215 i thought it is generally known that any non constant algebraic functions of 1 variable, applied to a transcendetal number, yield transcendental output.

comment what is the difference between $f(x;y)$ and $f(x|y)$?
@George that depends on the particular book you are looking at. Lots will use these notations to mean the same thing.
