Hi all,
I tried to use two equations to solve two unknowns, but it said cannot find answer because needing at least two arguments that is applied to 1.
I don't understand what that means. I have attached the worksheet and looking forward to hearing your solutions.
thanks
Solved! Go to Solution.
Your sheet was using the function In() function, not ln(). Mathcad won't evaluate In(A/D), that function requires two inputs.
View solution in original post
The function In() requires two arguments, you supplied one (A/D). Change to In(A,D), and your sheet calculates.
Many thanks for your replying, I tired to change to In(A,D) like you said it did calculate.
But it seems the answer calculated is slightly different due to In(A/D) and In(A,D) have a different meaning.
What do you think?
Appreciate your help, I saw I typed the wrong capital. Again, Many thanks
You had the modified second order Bessel function, not the natural log.
Please don't post the same question twice. I just answered on the other thread, only to find Fred had already answered on this one.
