Solving equation with conditional statements

Hello All,

I am trying to solve an equation that has condition statements and find the roots.

Please help,

Thanks

So you should solve the equation for q0 and not for B.f. You can make the solution a function of B_f as explained in my previous answer.

You may use either a solve block or the root function - its up to you.

You can speedup the calculation significantly (factor 5) by using the approach which I already showed in a previous posting

The symbolics can't do well with conditional expressions, so you should rather use Primes numeric methods (either a solve block with "find" or the "root" command.
I guess you rather want to solve for B.f and not for the function Deltaq(B.f)
Again you used function names as if it were simple variables! If you use a function, you have to provide the function argument!
