Evaluating $\int_{0}^{\frac{π}{2}} {(\frac{1}{\log (\tan x)} + \frac{1}{1 - \tan (x)})}^{3} d x$
Using the method shown here, I have found the following closed form.
$\int_{0}^{\frac{π}{2}} {(\frac{1}{\log (\tan x)} + \frac{1}{1 - \tan x})}^{2} d x = 3 \ln 2 - \frac{4}{π} G - \frac{1}{2},$
where $G$ is Catalan's constant.
I can see that replicating the techniques for the following integral could be rather lenghty.
$\int_{0}^{\frac{π}{2}} {(\frac{1}{\log (\tan x)} + \frac{1}{1 - \tan x})}^{3} d x$
My question: Could someone have, ideally, a different idea to evaluate the latter integral?

Does the logarithm inequality extend to the complex plane?
For estimates, the inequality $\log (y) \leq y - 1,$ $y > 0$ is often helpful. Is there any sort of upper bound for the logarithm function in the complex plane? Specifically, $| \log (z) | \leq$ something for all $z \in C$
Perhaps this would work?: $\log (z) \leq \sqrt{\log^{2} | z | + \arg (z)^{2}}$

I tried plotting the step and impulse responses in Matlab:
sys = tf([1 0],[1 -0.5])
figure(1);
step(sys);
figure(2);
impulse(sys);
However, both graphs look the same (can't post images of my graphs, I need more rep to do it).
Both graphs have exponential growth, but shouldn't the impulse response look like exponential decay?

Logarithmic equation
I'm studying logarithms and I encountered this equation:
$[\log_{9} (k + 1)]^{2} + \log_{9} (k + 1) + (k + 1) > 3$
I tried a lot but I still couldn't solve it! I know this may be easy for most of you but please could you help me?
Thanks!

Perimeter =48 m
Let the length be 𝑥 m and the breadth be 𝑦 m
As we know, Perimeter =2(𝑥+𝑦)=48 $\Rightarrow x + y = 24$ 𝑥+𝑦=24 [⋯(1)]
Area=135 m $^{2}$ .
As we know, Area=𝑙𝑏
Therefore, 135 m $^{2}$ =𝑥𝑦 [⋯(2)]

Proving a local minimum is a global minimum.
Let $f (x, y) = x y + \frac{50}{x} + \frac{20}{y}$ , Find the global minimum / maximum of the function for $x > 0, y > 0$
Clearly the function has no global maximum since $f$ is not bounded. I have found that the point $(5, 2)$ is a local minimum of $f$ . It seems pretty obvious that this point is a global minimum, but I'm struggling with a formal proof.

Fractions with sum 1
Using all numbers 0 to 9 only once, form two fractions whose sum is 1.
I have tried every possible combination but with no luck. I believe the fractions must be xx/xx + xxx/xxx but I am not sure. Any ideas are most welcome. I even tried getting all different ways to select 3 out of 10 digits, then omitting all the primes and trying to make fractions with simple values 1/3, 1/4, 2/5 etc using only different digits but again with no luck! By the way, two years ago I was given a similar one, with three fractions and without the digit 0, for which I found a solution 7/68+9/12+5/34 but now I am stuck!!
