反三角函数计算器app(反三角函数计算)
大家好,我是小五,我来为大家解答以上问题。反三角函数计算器app,反三角函数计算很多人还不知道,现在让我们一起来看看吧!
1、Sec(x) = 1 / Cos(x) Cos(x) = 1 / Sin(x) Cot(x) = 1 / Tan(x) Arcsin(x) = Arctan(x / 根号(-x^2 + 1)) Arccos(x) = Arctan(-x / 根号(-x^2+ 1)) + 2 * Arctan(1) Arcsec(x) = Arctan(x / 根号(x^2- 1)) + Sgn((x) - 1) * (2 * Arctan(1)) Arccsc(x) = Arctan(x / 根号(x^2- 1)) + (Sgn(x) - 1) * (2 * Arctan(1)) Arccot(x) = Arctan(x) + 2 * Arctan(1) HSin(x) = (E^(x) – E^ (-x)) / 2 HCos(x) = (E^(x) + E^ (-x)) / 2 HTan(x) = (E^(x) – E^(-x)) / (E^(x) + E^(-x)) HSec(x) = 2 / (E^(x) + E^(-x)) HCosec(x) = 2 / (E^(x) – E^(-x)) HCotan(x) = (E^(x) + E^(-x)) / (E^(x) – E^(-x)) HArcsin(x) = Ln(x + 根号(x^2+ 1)) HArccos(x) = Ln(x + 根号(x^2- 1)) HArctan(x) = Ln((1 + x) / (1 - x)) / 2 HArcsec(x) = Ln((根号(-x^2+ 1) + 1) / x) HArccsc(x) = Ln((Sgn(x) * 根号(x^2+ 1) + 1) / x) HArccot(x) = Ln((x + 1) / (x - 1)) / 2 Log n(x) = Ln(x) / Ln(n) 注: y=Sgn(x)符号函数:x>0时y=1;x=0时y=0;x<0时。
本文到此讲解完毕了,希望对大家有帮助。
