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...
sin^(-1)=arcsin，cos^(-1)=arccos，tan^(-1)=arctan。
最后,我们使用System.out.println方法打印结果。 反三角函数(inverse trigonometric functions) 在Java中,除了计算常见的三角函数值,还可以使用Math类的asin、acos和atan方法来计算反三角函数值。这些方法的结果以弧度为单位。 以下是一个示例代码,演示如何计算反正弦值、反余弦值和反正切值: doublesineValue=0.5;// 正...
Inverse Sine （反正弦）Arcsin(X) = Atn(X / Sqr(-X * X + 1))Inverse Cosine （反余弦）Arccos(X) = Atn(-X / Sqr(-X * X + 1)) + 2 * Atn(1)
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) ]
The value of arcsin 1 is equal to 90 degrees or π/2 radians. We can find the value of sin inverse 1 using the unit circle and its coordinates which are given by (cos x, sin x).
That is, if we let {eq}\theta {/eq} be the acute angle of a right triangle, the measure of angle {eq}\theta {/eq} can be determined through inverse sine function by, $$\theta = \sin^{-1} \left(\dfrac{\text{Opposite Side}}{\text{Hypotenuse}}\...
Inverse Sine Function: The inverse sine function has a domain of {eq}[-1, 1] {/eq} and a range of {eq}\left[ \frac{-\pi}{2}, \frac{\pi}{2} \right] {/eq}, as long as we're working with radians. If we try to evaluate the inverse sine...
