It's not for school... I am still learning mathcad that's the reason.ni tried but don't know what to use exactly..

Set your equation to 0 (zero) then use Root Finder Function
See the Help menu for instructions on using Root Finder.

sorry, should have looked at your profile first.

There are at least three ways to get answers in Mathcad:
> Numerical processor using the Given/Find or Given/Minerr, or Root Finder
> Symbolic processor can solve algebraic problems symbolically, on occasion
> Symbolic processor can also find roots numerically

E.g. see the attached - the second part is only to show it is the correct solution.

Hello Everyone
Thank you Occupant,IRstuff,Monkeydog for your help.

As in the given solution by Occupant do i have to manually select the value of "D" or i can make it automatic?

Thanks for your help.

I have to hit the road, but the answer is yes, you can make it automatic.

Also attached is the sheet itself. I wasn't sure that first set of brackets are actually necessary, so I included them. I upped the precision on the symbolic solver's solution so that the answers from the symbolic and numerical solvers came out the same. Note that the Given/Find requires a guess value for D, which was already calculated by the symbolic solver, but typically, anything close to the actual answer will work, and sometimes, even a guess that's far away will work as well.
