Inverse sine is one of the inverse trigonometric functions of the sine function and it is written as sin-1x and is read as "sin inverse x". Then by the definition of inverse sine, θ = sin-1[ (opposite side) / (hypotenuse) ]
然而它实际上只是sin的部分反函数(partial inverse)。因为sin不是双射函数(bijective),它的x和y不...
1. sininv cosinv taninv应该即系sin cos同tan既inverse function 即系例如当sin x = y既时候 sininv y = x. 而sinh cosh tanh叫做hyperbolic function. 在hyperbolic geometry入面 如果我地定义到一只直角三角形 咁呢个直角三角形既sin cos同tan既standard definition就系sinh cosh tanh. 2. In...

cos x)(cos x) tan² x = (tan x)² = (tan x)(tan x) 有2当然有3,sin³、cos³和tan³,相信你都估到代表甚么。不过,如果换成-1,不要把它当做倒数(reciprocal),因为它代表反三角函数(inverse trigonometric functions),定义如下: if sin x = n,sin^...
拉氏反变换 (Inverse Laplace Ttansforms) 拉氏反变换是拉氏变换的相反运算,也就是若 f(t)的拉氏变换是 F(s) (即 L[f(t)]=F(s)),则 F(s) 的拉氏反变换即为 f(t),记成: L^{-1}[F(s)]=f(t) 。到目前为止,囚拉氏反变换的方法有: ...
高等数学Mathematica实验题——1.2-29.反函数的求解及图形绘制 (Inverse Function Generation) “一般地,设函数y=f(x)(x∈A)的值域是C,若找得到一个函数g(y)在每一处g(y)都等于x,这样的函数x= g(y)(y∈C)叫做函数y=f(x)(x∈A)的反函数,记作y=f^(-1)(x) 。反函数y=f ^(-1)(x)的定义...
反三角函数(inverse trigonometric function)是一类初等函数。指三角函数的反函数。由于基本三角函数具有周期性,所以反三角函数是多值函数。这种多值的反三角函数包括:反正弦函数、反余弦函数、反正切函数、反余切函数、反正割函数、反余割函数,分别记为Arcsin x,Arccos x,Arctan x,Arccot x,Arcsec...
Inverse sine function Thearcsineof x is defined as the inverse sine function of x when -1≤x≤1. When the sine of y is equal to x: siny=x Then the arcsine of x is equal to the inverse sine function of x, which is equal to y: ...
