HP Prime can solve 2 equations with 2 variables in trigonometric functions ?

That's the Equation System, the second variable is inside the cos and sin function. How can I Solve this system on HP Prime ?

In many cases, you don't even need to supply seed values at all; pressing Solve will use the default seed values that are already there.  As explained in the User Guide, supplying seed values helps the solver know where to start looking for the solutions.  The seed values will be replaced with a solution.  If your system of non-linear equations has more than one solution, you can steer the solver towards them by supplying different seed values. 

 

As Maké indicated, make sure that all the equations are selected (with a check mark) in the Solve Symbolic View.  That lets the Solver know that it's a system of simultaneous equations.

 

Hope that helps!  Disclaimer: I don't work for HP.
