Hi,
Solving nonlinear equations using FindRoot gave me following error
Error: 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.
Code is given below:
I used options WorkingPrecision of 30 but issue wasn’t sort out.
Do I need to add other options or not so please someone help me to correct this error?
