$\cos (0) = \frac{\sqrt{2}}{2}$

Subtract $\frac{\sqrt{2}}{2}$ from both sides of the equation.

$\cos (0) - \frac{\sqrt{2}}{2} = 0$

The exact value of $\cos (0)$ is $1$ .

$1 - \frac{\sqrt{2}}{2} = 0$

The expression is constant, which means it can be rewritten with a factor of $x^{0}$ . The degree is the largest exponent on the variable.

$0$
