document.write( "Question 806606: I need help finding all angles where 0 is less than or equal to t and t is less than 2pi.
\n" ); document.write( "My problem is cos t= radical 2 divided 2. Given the bounds I know that on the quadrants, 0 and 2pi is along the x axis and seems to be located in the middle of the 1st and 4th quadrant. Now the directions specify the given condition, so if 0 and 2pi are in the middle of those two quadrants, how would I go about finding the angles? \n" ); document.write( "
