用C语言写了个数学公式出现error C2064:term does not evaluate to a function
double N,Ra,S,S12;
S12=579.5888;N=a*a/(b*sqrt(1+e12*cos(B1)*cos(B1)));Ra=N/(1+e12*cos(B1)*cos(B1)*cos(A1)*cos(A1));S=S12*sqrt((1-(H2-H1)*(H2-H1)/(S12*S12))/((1+H1/Ra)(1+H2/Ra)))+S12*S12*S12/(24*Ra*Ra);//S=S12*sqrt((1-((H2-H1)/S12)*((H2-H1)/S12))/((1+H1/Ra)(1+H2/Ra)))+S12*S12*S12/(24*Ra*Ra);printf("大地线长度S=%lf\n",S); 就是S=……这个公式

double N,Ra,S,S12;
S12=579.5888;
// a没有定义,也没有赋值,b没有定义和赋值,e12没有定义和赋值,B1没有定义和赋值
N=a*a/(b*sqrt(1+e12*cos(B1)*cos(B1)));
// A1没有定义和赋值
Ra=N/(1+e12*cos(B1)*cos(B1)*cos(A1)*cos(A1));
// H1、H2没有定义和赋值
S=S12*sqrt((1-(H2-H1)*(H2-H1)/(S12*S12))/((1+H1/Ra)(1+H2/Ra)))+S12*S12*S12/(24*Ra*Ra);
//S=S12*sqrt((1-((H2-H1)/S12)*((H2-H1)/S12))/((1+H1/Ra)(1+H2/Ra)))+S12*S12*S12/(24*Ra*Ra);
printf("大地线长度S=%lf\n",S);
再问：哦谢谢是我代码没有写完其实是有赋值的原来错在有两个数相乘我居然没有用*
