Answer 34

@someusername Please don't give out answers without explanations. It does not help the user learn, and is in fact against the OpenStudy Code of Conduct.

Answer 35

She's the one giving out answers, I'm telling her if she's right or wrong.

Answer 36

Sorry, I won't answer questions without explanations. I just figured most people honestly don't care about our explanations, they just want the answers.

Answer 37

@someusername

17 minutes ago, you posted: "Correct answer is A."

OpenStudy do care about explanations a lot more than answers, however people just want to get their homework done and become lazy at times.

Answer 42

Sec is the opposite of sin right

Answer 43

@LilySwan Correct. It's just an convenient way of saying \(\frac{1}{sin\theta}\).

Answer 44

but why is my calculator not calculating sec(-270)

Answer 45

It says error

Answer 46

would it be undefined

Answer 47

@LilySwan Your calculator handles trig function with negative values in a different way. Firstly remember that you must switch to degree mode. If that does not solve the problem, you will need to remember the four quadrants and the relevant rules about angle identities in order to solve this question.

Remember that sec(-270) = csc(-90).

Answer 48

is it 1.01

@tyteen4a03

Answer 50
