ASIN(3G)

✨ ASIN — ok bestie, let's talk arcsine ✨

hey hi hello 💖 this is the asin page from the [FIXME: manual] — yes the manual name is literally a FIXME, we don't ask questions, we just vibe 🫶

---

🌸 NAME 🌸

asin — return the arcsine of the parameter. that's it, that's the whole job 💅

---

🎀 DECLARATION 🎀

genType asin(genType x);

look at her. one line. iconic. ✨

---

🦋 PARAMETERS 🦋

• x — the value whose arcsine you want back, babe. hand it over and it'll do the math 🧚

---

💜 DESCRIPTION 💜

so, plot twist: the manpage literally says

"atan returns the angle whose trigonometric sine is $x$."

and we're keeping that exactly as-is because the facts do not change, even when they're a lil typo-coded 🙈 (yes it says atan, yes this is the asin page, no we are not touching it, moving on 💀)

anyway — asin gives you back the angle whose trigonometric sine is $x$. 🔥

the range of values returned by asin is $[-{\pi \over 2}, {\pi \over 2}]$ ⭐

result is undefined if $\left| x \right| > 1$. like, genuinely undefined, no cap. don't feed it a value with absolute value bigger than 1, bestie, it will not go well 😭
