$\sin^{2} (x) + \cos^{2} (x) = 2$

Step 1

Subtract $2$ from both sides of the equation.

$\sin^{2} (x) + \cos^{2} (x) - 2 = 0$

Step 2

Simplify $\sin^{2} (x) + \cos^{2} (x) - 2$ .

Step 2.1

Apply pythagorean identity.

$1 - 2 = 0$

Step 2.2

Subtract $2$ from $1$ .

$- 1 = 0$

$- 1 = 0$

Step 3

Since $- 1 \neq 0$ , there are no solutions.
