Find all values of t in the interval [0, 2π] satisfying the given equation. (Enter your answers as a comma-separated list.)
(4 cot t)^2 = 48
take sqrt of both sides
4cot t=√48=4√3
cot t=(4√3)/4
..
cot t=(4+√3)/4
t≈1.04, 4.18 (radians) (In quadrants I and III where cot>0)
..
cot t=(4-√3)/4
t≈1.94, 4.34 (radians) (In quadrants II and IV where cot<0)
