	1、 三角函数 
　　double sin (double);正弦 
　　double cos (double);余弦 
　　double tan (double);正切 
　　2 、反三角函数 
　　double asin (double); 结果介于[-PI/2, PI/2] 
　　double acos (double); 结果介于[0, PI] 
　　double atan (double); 反正切(主值), 结果介于[-PI/2, PI/2] 
　　double atan2 (double, double); 反正切(整圆值), 结果介于[-PI, PI] 
　　3 、双曲三角函数
