Solve the equation and find all real solutions:
(sinx +cosx)^2 = 1.
------------------------------------
Open parentheses and then simplify
= ,
1 + 2*sin(x)*cos(x) = 1, <------ =
2*sin(x)*cos(x) = 0,
sin(2x) = 0, (formula of the double argument for sine)
2x = , k = 0, +/- 1, +/- 2, . . . (integers)
x = .
