# “This system cannot be solved with the methods available to Solve” What should be done in such case? [duplicate]

What can I do to solve this task?

Solve[Power[x, 2] + Power[y, 2] + 1 == cos[Power[x, 2]*Power[y, 2]], {x,
y}]


Reduce[Power[x, 2] + Power[y, 2] + 1 ==

• Also, Solve[Power[x, 2] + Power[y, 2] + 1 == Cos[Power[x, 2]*Power[y, 2]], {x, y}, Reals, Method -> Reduce] – Bob Hanlon May 29 at 15:39
