: : : 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.

: : yes I want to solve for x, no i did not pull these questions out thin air, and yes I copied them correctly:

: : 7) sin x = 1.364    x=________
: : 8) cos x = 2.456    x=________

: : And here's another one that I found:
: : Write all the angle values:
: : 8) arccos 1.45123 = _________

: : What I think she wanted me to do was subtract 1 (representing 360 degrees) and then find the angle that has the difference for cos or sin:

: : 7) sin x = 1.364
: :      1.364 - 1 = .364
: :      sin x = .364

: : but that still doesn't help b/c no non-fractional angle has that for sine

: : Oh well, I'll just try to reason with the retard tomorrow morning for her to explain it to me. You have no idea how much this woman aggravates me!!

: : And the place where I got these problems was from her very own worksheets that she made like 90 million years ago when she first started teaching.

: If those are the questions, then the answer to each of them is, "This cannot be solved because the stated value is outside the range of possible values for sine/cosine."

: Take a deep breath & go on to something else.
: :-)

Thanks.... I don't know what to do with myself now.. all this free time PLUS i don't have to deal with her at quarter of 7! Thanks again!
