comment Prove that if b is coprime to 6 then $b^2 \equiv 1 $ (mod 24)
Since $b^2$ is a perfect square, we have that $b^2 = 1,4,9,16$ modulo $24$. All of these, besides $1$, require that $2 | b$ or $3 | b$.

@Wolff Think inverse trigonometric functions.

comment Real Analysis Question concerning existence of curve and derivative?
Suppose $f(0) \ne 0$. Use continuity of $f$ to obtain a contradiction.

comment % of my equivalent human life hunting a fly for 5 minutes before I kill it, if its lived for 3 days and myself for 40 years
House flies usually live for 15 to 30 days once hatched from pupal stage, though you may very well have been chasing a 3-day-old fly.

comment Does an element of a group to the 0th power equal the identity?
In other words, the assignment of $x^0 = 1$ plays nice with $x^ax^b = x^{ab}$ for all $a$ and $b$, a desirable property.

comment Does this equation have positive integer solutions?
In other words, combining any two Pythagorean triples gives a solution.

comment How do I show using math symbols “get quotient without remainder”
Try $\lfloor 10/3 \rfloor=3$. This is the "floor" operation and gets rid of any decimal.

comment How find this integral
Your bounds are for $t$, but you treated them as if they were for $\theta$. Notice that $\theta = \sin^{-1} t$, so you can easily switch back.
