In Exercises 31–38, find a cofunction with the same value as the given expression.cos 2𝜋5

Accepted Answer

Hello everybody. I have married today. Today we're going to again this question that states which of the following coal functions has the same value as cosine of open parentheses. Five pi divided by 17 closed parentheses where the answer choices are a sign of open parentheses. 14 pi divided by 17 closed parentheses. B is sign of open parentheses. Nine pi divided by 34 closed parentheses. C is sign of open parentheses. Seven pi divided by 17 closed parentheses and D his sign of open parentheses. Seven pi divided by 34 closed parentheses. Now, when tagging in this question, we should note the rule of complementary angles and code functions here that we have of sine and cosine. So we should note that sign of minus theta is equal to cosine of the. Now, in our case, 90 can be represented as pi over two. So we can have that sign of open parentheses. Pi divided by two minus potato is equal to cosine data. So they gave us that cosign is five pi divided by 17. So we have that equal to sign of open parentheses pi divided by two minus theta. And in this case, our theta is that five pi divided by 17. So using that rule, we can simplify all we have to do now is just simplify. So we have that sign of open parentheses pi divided by two minus five pi divided by 17 closed parentheses. That would be equal to sign of open parentheses. Seven P divided by 34. And that would be the co function that has the same value as the cosine function given or in this case, answer choice. So thanks to that simple rule that we have for co functions and complementary angles, we were able to calculate the corresponding co function to the cosine function that was given. So I hope that was helpful. And until next time.
