How to write this mathematical formula in C++?

Question

I have a simple formula and I want to use it in C++ application. Not sure how to rewrite in C++.

so why the c tag, c++ is different from c. ok please remove the c tag — Seek Addo, Feb 19 '17 at 12:49
where is the integral in this? (btw. you usually approach integrals by discretizing & summing). — lorro, Feb 19 '17 at 12:57
We do people answer him? He didn't put any snippet of his own, he clearly wants someone to do it for him — user3104201, Feb 19 '17 at 13:14

logn(5, abs((a*b - d*c) / (tan(c) + sin(d))))

where logn is:

double logn(double base, double x) {
    return log(x) / log(base);
}

and the header cmath is included for the other functions.

You can do this, be careful with libs, namespaces, and radian arguments

z = a*b - d*c; 
s = tan(c) + sin(d);
num = abs(z/s);
log(num)/log(5);
