Asinh – giperbolik arksinus

• function asinh($x) { return ln($x + sqrt(1 + pow($x, 2))); }
• Windows ot uchun to’g’irlangan asinh

Atan2(float $y, float $x) – arktangens 2 argumentli funksiyasi $y bo’linuvchi $x bo’linma atan(float $num) – arktangens x == atan(tan(x)) faqat atan diapazonida bo'lgan x uchun, ya'ni -pi/2 < x < pi/2 bo'lgan x uchun amal qiladi. Atanh(float $num) – giperbolik arktangens
