Question
solve for 0 <= x <= 2pi. leave answers in terms of pi.
1) tan x= cot x (find all 4 solutions for the 4 quadrants)
tan(x) = cot(x)
tan(x) = 1/(tan(x))
(tan(x))^2 = 1
tan(x) = ±1
inverse tan both sides
in degrees x = 45°, 135°, 225°, and 315°
45° and 225° would equal 1
135° and 315° would equal -1
in terms of pi,
45° = (pi)/4)
135° = (3pi)/4
225° = (5pi)/4
315° = (7pi)/4
