Answer:
C
Step-by-step explanation:
Citizens are not given the correct information.
Answer:
<em>B. 0² + (-1)² = 1</em>
Step-by-step explanation:
Given the equation sin^2(pi)+cos^2(pi)=1
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>
