No coordinates given in the problem. I always make an effort. Please, read my entire signature.

Is the length BA cosx? Is OA sinx? Is OB the hypotenuse 1? I was not able to determine the coordinates for A and D.
You say 'express the lengths in terms of x' but when your picture shows "x" only as the x-axis, not as a length.
Originally Posted by nycmath Is the length BA cosx? Is OA sinx? BACKWARDS Is OB the hypotenuse 1? CORRECT I was not able to determine the coordinates for A and D. , means length. And Can you tell us why?

Thank you, Plato. I will work on this more on my next day off, which is Monday. This question is from a chapter titled Right-Triangle Trigonometry. A very cool topic.
