Avoid machine precision issues while using FindRoot?

Muhammad Atif Masoud
Posted 6 years ago

I am facing Precision error in Find Root FindRoot::lstol: The line search decreased the step size to within tolerance specified by AccuracyGoal and PrecisionGoal but was unable to find a sufficient decrease in the merit function. You may need more than MachinePrecision digits of working precision to meet these tolerances.

Sir my question is that what will be the command to remove this error. I attached the relevant computation. You can see the following errors in it. Normally when i do such type of calculations which are very smooth and fast.
