Question

Which equation shows that the pythagorean identity is true for Ø=pi? select the equation that is the form sin^2(pi)+cos^2(pi)=1

Answer 1

Answer: For This Specific Question it is B, But there is a question very similar that doesn't have the pi's in the equation and the answer to that one is A.

Step-by-step explanation: Very sorry if this is confusing :)

Answer 2

Answer:

B. 0² + (-1)² = 1

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

Hence the correct equation that shows that the pythagorean identity is

0² + (-1)² = 1. Option B is correct.
