Use an algebraic method to find the solution for 0<=x<=2pi of the equation
5cot x + 2cosec^2 x = 5
***

csc^2(x)=cot(x)+1

(cot(x)+3)(2cot(x)-1)=0
cot(x)=-3
(Using inverse tan key of calculator set to radians)
x≈2.82, 5.96 (In quadrants II and IV in which cot<0)
or
cot(x)=1/2
x≈1.11, 4.25 (In quadrants I and III in which cot>0)
