slava [35]

Answer:

<em>B. 0² + (-1)² = 1</em>

This can also be written as (sinπ)² + (cosπ)² = 1

According to trigonometry Identity;

sinπ = 0 and cosπ = -1

Substituting this values into the expression  (sinπ)² + (cosπ)² = 1 will give;

0² + (-1)² = 1

<em>Hence the correct equation that shows that the pythagorean identity is </em>

<em>0² + (-1)² = 1. Option B is correct.</em>
