: I've been out of school for the past couple of days so I've missed some classwork in math that will be on the test tomorrow and that the teacher will not go over with me b/c Pre-Calc help is on Tuesday and that I should have gone to see her on Tuesday (b/c of course I knew I needed help before I got the worksheets) Here's my question:

: How exactly do I go about solving this type of problem without using decimals or a calculator:
: 1) sin x = 1.364
: 2) cos x = 2.456

: Is there an equation on how to solve this? I'm very lost!

And you want to solve for x?

Where did you find such a problem? These are impossible because for all values of x:
-1 <= sin x <= 1
-1 <= cos x <= 1

If you find a question in your textbook, notes, or homework that is and example of what you are asking, please post it EXACTLY as it was given to you.
