# Which statement(s) are true based on the pythagorean identities? sine squared (theta) = 1 cosine squared theta 1 = secant squared

Which statement(s) are true based on the pythagorean identities? sine squared (theta) = 1 cosine squared theta 1 = secant squared theta minus tangent squared theta cotangent squared theta = cosecant squared theta minus 1 1 minus tangent squared theta = negative secant squared theta negative cosine squared theta = sine squared theta minus 1

The statement that is true based on the Pythagorean identities is  cotangent-squared of theta – cosecant-squared of theta = -1.

### Why is the equation  above true?

Note that cotangent-squared of theta – cosecant-squared of theta = -1. is tru because it is the only equation that is correct.
So therefore,  cotangent-squared of theta – cosecant-squared of theta = -1.
