comment Why is treating $i$ as a constant in integration, valid?
@Aditya Agarwal If you have $\int i f(x)dx$, where $f(x)$ is real, then this integral "sits" on the imaginary axis, and since integration is linear we can rewrite this as $i\int f(x)dx$. This still "sits" on the imaginary axis. So there is no confusion between "imaginary or real slopes" at all. $i$ is a constant.

comment Can all real numbers be represented by the sum of a convergent series?
Your sum is trivial since if we let $x=2$, we get $\sum_{n=0}^\infty\frac{1}{2^n}=2$. Hence you can choose $k$ and $m$ such that $\frac{k}{m}\cdot 2=\ell$, where $\ell\in\mathbb{Q}$ is any rational you like.

comment Find all complex numbers $z$ satisfying the equation- $|z + 1| = |\bar{z} − 1|.$
General tip: When presented with a problem like this, think about what you know. A few "facts" that spring to my mind immediately are: $|w|^2=w\bar{w}$, and for $w=x+iy$ then $\bar{w}=x-iy$. See also Daniel Fischer's comment. Apply what you know and see what follows logically. Hopefully it will be the answer!

comment Turning 500, 1100, 1800, 2600, 3500, etc into 1, 2, 3, 4, 5, etc
We have $f (n) = 50 n(9 + n)$, so just use the quadratic formula to get $n$.

comment Evaluating This Complex Line integral
Yes. But as you say it's rather ugly ! See Jack's answer below...

comment Evaluating This Complex Line integral
You could try letting $z=\sin(t^2)-i\frac{2t^2}{\pi}$ and substitute into the integral. Use the limits $0$ and $\sqrt{\pi/2}$. But maybe you tried that already.

comment Abuse of notation ? $(A\mid M_{n\times p})$ to denote a set of matrices…
@A.G. Good point !
