Move all terms not containing $x$ to the right side of the equation.

$- x = - 2$

Divide each term in $- x = - 2$ by $- 1$ and simplify.

$x = 2$

Characteristic function of logarithm of random variable
If I know the characteristic function

ϕ_{X} (t)

of a random variable

X > 0

, how can I write the characteristic function

ϕ_{Y} (t)

Y = \log (X)

?
I know that

ϕ_{X} (t) = E [e^{i t X}]

and

ϕ_{Y} (t) = E [e^{i t \log (X)}]

. But I can't derive one from the other. Any idea? I would like to use

ϕ_{X} (t)

to calculate the second moments

Integer solutions to fraction equation
I am having trouble finding all solutions (or at least proving I have all the solutions already).
The equation is

\frac{1}{a} + \frac{1}{b} + \frac{2}{c} = 1

*a,b,c are positive I tried to base it on the solutions of a similar equation with the last term a 1 instead of a 2.

Finding unknown in log equation
I was given a log equation:

D = 10 \log (I / I_{0})

I

is the unknown in this case,

I_{0} = 10^{- 12}

and

D = 89.3

I did the following steps:

\begin{aligned} 89.3 & = 10 \log (\frac{I}{10^{- 12}}) \\ \frac{89.3}{10} & = \log (\frac{I}{10^{- 12}}) \\ 8.93 & = \log (\frac{I}{10^{- 12}}) \end{aligned}

I'm not quite sure how to isolate I after step 3, and I'm also unsure if dividing

89.3 / 10

is correct as well. So how can I find the unknown (

Why does the same inequality give different answers?

(\log_{2} (x) - 2) (\log_{2} (x) + 1) < 0

has a solution

\frac{1}{2} < x < 4

But when we take the second part alone that is

(\log_{2} (x) + 1) < 0

it gives a solution

0 < x < \frac{1}{2}

why is

x > \frac{1}{2}

in the first case but

x < \frac{1}{2}

in the second case?

The limit of a sequence
Given

x_{n} = \frac{1}{n^{2} + 1} + \frac{1}{n^{2} + 2} + \frac{1}{n^{2} + 3} + \dots + \frac{1}{n^{2} + n}

Verify if there is or no a limit. Find it if affirmative.
Let

a_{n} = \frac{n}{n^{2} + 1}

(The biggest portion of the sum

n

times) and

b_{n} = \frac{n}{n^{2} + n}

(the smallest portion of the sum

n

times) then

b_{n} \leq x_{n} \leq a_{n}

b_{n} \leq x_{n} \leq a_{n}

since

lim \frac{n}{n^{2} + 1} = lim \frac{n}{n^{2} + n} = 0,

we have that

lim x_{n} = 0.

Is this wrong? why? If it is, any tips on how to find

lim x_{n}

? Grateful for any help.
