Help me solve this non-linear equation.

Hello, I am new to MATLAB and I am trying to solve this non-linear equation, but the command windows said there is no solution found. Is this the right answer? Please see the picture attached in this questions. this is my code:

function z=eqns(x)
z(1)=sin(x(1).*x(2))^2;
z(2)=cos(x(1).*x(2)); 
end

Command Window:

>> solution = fsolve(@eqns,[-pi pi])

No solution found.

fsolve stopped because the last step was ineffective. However, the vector of function values is not near zero, as measured by the default value of the function tolerance.

solution =

   -3.1953    3.1953

Thanks

Before using MATLAB, you should think about the math. Suppose that y = x(1)*x(2). You are trying to solve

sin(y) = 0
cos(y) = 0

(if sin(y)^2=0 then sin(y)=0). Does this have any solutions?

Thanks for your fast respond I was able to solve it thank to your answer.

I hope your answer was no solutions!
