Question

Is square root 1 minus sine squared theta = cos Θ true? If so, in which quadrants does angle Θ terminate?

Answer 1

I believe the answer is True; quadrants I & IV, can anyone confirm?

Answer 2

\[\cos^{2}x + \sin^{2}x = 1\]

Answer 3

That's true for all angles I believe...

Answer 4

Because the values of cosine and sine will be squared, so the answer will always be positive.

Answer 5

False

True; quadrants I & IV

True; quadrants II & III

True; quadrants I & III
These are my choices.

Answer 6

Err, not sure what it means when the angle terminates. But that property should work for all angles lol

Answer 7

Then 'false' would be my answer.
