Solve the system of equations :
x + y = 
, sin x + sin y = 
and x, y ∈ 
Text Solution
Verified by ExpertsThe correct answer is:
CHECK THE SOLUTION.
x = 
, y = 
or x = 
, y = 
.
We have, x + y = 
and cos x + cos y = 
Now, cos x + cos y = 
⇒ 2 cos 
cos 
= 
⇒ cos 
= 
[using x + y = 
]
Clearly, cos 
= 
is not possible.
Hence the given system of equations has no solution.
