comment Trig Fresnel Integral
I'm not sure, would $\dfrac{1}{x^2} \times (-cos(x^2))$ be correct?

comment Find Line with specific Angle to another Line
@exploringnet You have just removed my addition with $cos(\phi)$ with your edit. Could you please add it? Edit: Nevermind, did already

comment Find Line with specific Angle to another Line
1) It should be the multiplication symbol, $|A_\vec{D}|$ is a single number. (The length of the vector $\vec{D}$). What symbol should I prefer? 2) Oh yes, you are right! Thanks

comment Find Line with specific Angle to another Line
@exploringnet: I know. Please read my last sentence: The equation may require another angle γ that defines the banking of the new line on the other.

comment How to find perpendicular vector to another vector?
What is this kind of notation called? I have never seen a vector being defined like $(3i + 4j - 2k)$. The notation I've seen so far would be $\left(\begin{array}{c}3\\4\\2\end{array}\right)$, therefore I do not really understand your answer. :(

Definately a nicer than using $cos$ and $sin$. I sure wouldn't have come to this equation. Thank you!

comment Finding a function that computes a point on the unit-circle
@AndréNicolas I didn't say, I wanted the function to replicate the whole unit-circle, the resulting point just needs to lie on it. Maybe my edit makes it more clear. Thanks to everyone who offered his help.

Sorry, mistyped. I meant $f(x) = cos(sin^{-1}(x))$ which actually seems to work well.

@Emre Oh man, simpler than I thought. Headache, you know? ;-) $f(x) = cos(sin(x))$ ?

Awesome, really. Just great. Thank you very much.
