math.tan()## 原型:math.tan(x) 解释:返回一个数x的对应的正切值,x的角度是弧度。 math.asin()## 原型:math.asin(x) 解释:返回一个数x的反余弦值,返回值的单位是弧度。 math.acos()## 原型:math.acos(x) 解释:返回一个数x的反余弦值,返回值的单位是弧度。
Math.PI 记录的圆周率 Math.E 记录e的常量 Math中还有一些类似的常量,都是一些工程数学常用量。 Math.abs 求绝对值 Math.sin 正弦函数;Math.asin 反正弦函数 Math.cos 余弦函数;Math.acos 反余弦函数 Math.tan 正切函数;Math.atan 反正切函数;Math.atan2 商的反正切函数 ...
C++中的cmath库提供了一些函数来计算三角函数,如sin、cos、tan、asin、acos、atan等。这些函数需要传入一个角度值(弧度制或角度制),然后返回相应的三角函数值。下面是一些示例代码: #include <iostream> #include <cmath> int main() { double angle = 45; // 45度 double radian = angle * M_PI / 180...
TheMath.tan()method expects the number in radians. Based on sine and cosine: Math.tan(x) = Math.sin(x) / Math.cos(x). What is Radians? Radiansis an angle'sαamount of rotationbon a circle: DegreesPIRadians 0°00 1°PI/1800.0175 ...
