RE: Using fsolve() to solve nonlinear system equation
For fsolve(), yeah you are right. we need to try different initial guess. It works somehow. But it will be great if we can specify the range that fsolve() to find the solution which is available for one variable, but not multiple variables, as parisse said.
For solve({x+y=5*Pi/4, tan(x)=1},{x,y}), I though solve() will give a complete solution, as it solved symbolically.
