Using solve and sigma from programming
Hello,
I have an equation pv = cf/(1+r) + cf/(1+r)^1 + cf/(1+r)^2 + ... + cf/(1+r)^n I have the value of pv, cf and I need to find the value of r. How do I call the CAS.solve() and pass a function that does summation? BEGIN LOCAL pv,cf,result; pv:= 100; cf:= 10; result:=CAS.solve(.....); // < how do I write this? END;

I deleted my previous post because i had an error in the program.
I'm thinking this: PHP Code: EXPORT testsum() is what you are looking for? road
