Solve for 0¡Üx<2¦Ð. Round to nearest hundreth of a radian.
secx=2cscx
Your 0¡Üx<2¦Ð is illegible. I will assume that you mean 0 < x < 2 pi
2 cscx = 2/sinx, so
1/cosx = 2/sinx
tanx = 2
x = 1.107 radian and pi + 1.107 radian = 4.249 radian
Round them off to a hundredth radian, since they ask for that
