im working on the "marine biology casestudy" thing in class, and im using vc++ for the compiler. I have one function that is meessing up my position of seacrabs on the bottom. It takes 2 heigth and a position betheen them and uses (pos(tan((a-b)/1)))+a or (pos(tan((b-a)/1)))+b whather a is > b. But when i pass it these floats a = 3 b = 1.7787 pos = 0.9 it returns 4.24809 it should return 1.79788 this is the code that i am using. i have the c2 there for debugging. float findtrianglespot(float a,float b,float pos) { float e; //ofstream c2("debug2.txt"); //c2 << a << char(10)< b) { e = tan((a-b)/1.0); //c2 << (pos * e) + b; return( ((pos * e) + b) ); } else if (a < b) { e = tan((b-a)/1.0); //c2 << (pos * e) + a; return( ((pos * e) + a) ); } else { return(a); } //c2.close(); }

I fixed it, I was using degrees, when tan takes radians. I hate when that happens.
