comment Why doesn't this integral from zero to infinity contain $exp(\infty)$?
your exponent values are negated in the $t$ limits due to the term $-(iy+\alpha)t$; these naturally $\rightarrow 0$ by definition.

comment Why $E^2$ instead of $\Bbb R^2$
$\mathbb{R}^{2}$ is the space of "doublets" $(x, y)$ such that both $x, y \in \mathbb{R}$ - the plane if you like is non-defined.

comment Why $E^2$ instead of $\Bbb R^2$
It just refers to the Euclidean plane; so formally, the polar coordinate functions take values in $E^{2}$ and map them to the reals.

comment d'Alembert Solution of fixed end
Remember that the solution is a sum of two travelling waves one moving to the right and one to the left; the shape of these individual arbitrary functions with respect to x stays constant, however the functions are translated left and right with time at the speed c.

Was it originally an $\arccos$ in the inital question or $\cos$ multiplied by a constant $A$?

comment Mean Squared Error
In nearly $20$ years of using both statistics (and other frequently used measures of estimators) I have never seen greek symbols for them. Simply, I use MSE and RMSE etc...
