I am trying to recreate an equation in mathCAD from an algorithm formed in in Excel. I know the general format of the of the equation (C*e^-kx), I know x is the variable and I know the constant C and all of the factors that contribute to the formation of k but I don't know how each input contributes to k. I am wondering if any of you know of a function in MathCAD (or even excel) to where I can plug in k and all of the variables that contribute to k and solve for the signs (X/+-) that make a pool of factors equal k. If it really comes down to it I will have to plug and chug to find the order of operations to take my variables constitute k. This is not for school this is not for job/money, only personal a pet project to clear one's mind. So does a function of this power exist?
