Question

C#中如何把下列数学表达式,改写成等价的C#表达式?

Answer 1

(1)double func(double x,double y){ return (1+y/x)/(1-y/x);}

(2)double func(double x,double y）{return x*x + (3*x*y)/(2-y);}

(3)double func(double x){ return ((1+x)*(1+x))/(1-x*x) - 1;}

(4)double func(double a,double b,double c){return System.Math.Sqrt(System.Math.Abs(a*b - c*c*c));}
