 Sep 27 awarded Student May 1 comment Trig Fresnel Integral I'm not sure, would $\dfrac{1}{x^2} \times (-cos(x^2))$ be correct? Apr 30 awarded Commentator Apr 30 revised Find Line with specific Angle to another Line Corrected formula in #2 Apr 30 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 Apr 30 revised Find Line with specific Angle to another Line Corrected equation in #2 Apr 30 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 Apr 30 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. Apr 30 asked Find Line with specific Angle to another Line Oct 30 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. :( Jan 23 accepted Finding a function that computes a point on the unit-circle Jan 23 comment Finding a function that computes a point on the unit-circle Definately a nicer than using $cos$ and $sin$. I sure wouldn't have come to this equation. Thank you! Jan 23 awarded Editor Jan 23 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.

I meant $f(x) = cos(sin^{-1}(x))$ which actually seems to work well. Jan 23 comment Finding a function that computes a point on the unit-circle @Emre Oh man, simpler than I thought. Headache, you know? ;-) $f(x) = cos(sin(x))$ ? Jan 23 asked Finding a function that computes a point on the unit-circle Oct 20 awarded Supporter Oct 20 awarded Scholar
