Explanation Another way of asking this question is "the tangent of what angle gives me sqrt3/3?" We know that " "tanpi/6=sqrt3/3. So then, " "" "tan^-1sqrt3/3=pi/6 Note that even though tangent is positive in the third quadrant, and that the tangent of an infinite amount of coterminal angles is sqrt3/3, we need to observe that the range of tan^-1x is -pi/2,pi/2, so only pi/6 is a valid answer within this range.
Inmost (scholar) questions like this one, the simplest way is to give names to the different atan−1(). Set a = atan−1(x) ↔ tan(a) = x and b = tan−1(y) ↔ tan(b)= y Find points on curve r = 2sinθ where the tangent line is parallel to the ray θ = π/4
The principal value branch of tan-1 x is `(- π/2, π/2)`.. Let tan - 1 (- √3) = α, where `(-π)/(2) ≤ α ≤ π/(2)`. ∴ tan α = - √3 = - tan `pi/(3)` ∴
