Now just another ordinary stupid NEET. Abstract Algebra has always been my enemy, now I am trying to conquer it.

comment I have a question about integrating, and what to do about the constant. $\displaystyle\int\frac{1}{1-z}dz$
If you know the initial value of the function, then the value of the constant can be determined. In this case, the value of the function at $x=0$ is zero. Because we know that sum of zeros is zero.

let $y=a-x$ then usual substitution

@user101998 how about using formula $\sin(a+b)$ ??

comment When does $\ln(x)=\sin(x)$?
looks like there is no nice expression for the answer. You can use numerical approach the find the approximate value.

comment Examining the convergence of $\int_{1}^{\infty}\frac{1}{x^2+x}\text{ d}x$
how about $$\int_1^\infty \frac 1 x dx - \int_1^\infty \frac 1 {x+1} dx=\int_1^2 \frac 1 x dx +\int_1^\infty \frac 1 {x+1} dx- \int_1^\infty \frac 1 {x+1} dx$$

comment Answer difference of same series with different index
because of the index since it starts with zero while other starts with 1 ... on second series you get extra $3$
