You can put this solution on YOUR website! The inequality sin theta >(or equal to) cos theta is true for all values of theta in the interval
A. 0 degrees < theta < 90 degrees
B 0 degrees < theta < 360 degrees
C. 45 degrees < theta < 225 degrees
D 45 degrees < theta < 315 degrees
***
In quadrant I, for x≥45˚, sin≥cos
In quadrant II, sin>0, cos<0
In quadrant III, for x≤225, cos is equal to or more negative than sin, that is, sin ≥ cos
ans:C. 45 degrees < theta < 225 degrees
