Concept Check What is wrong with the following item that appears on a trigonometry test? "Find sec θ , given that cos θ = 3/2 . "

Check whether the following statement is possible or not where the value of sequent data is 3/5. If cosine data is five thirds, now we can solve this by making use of the domain of cosine. Now we know cosine data cannot be larger than one has be between negative one and one. Our cosine data is five thirds, cosine data equaling five thirds is greater than one. This means this is not possible. Additionally, because cosine data has to be between negative one and one second data can only be larger than one or less than negative one since the is 3/5 that does also does not follow with the condition. This means this is impossible. OK. I hope to help you solve the problem. Thank you for watching. Goodbye.
