f(x) = tan2(x) + (√3 - 1)[tan(x)] - √3 = 0
tan2(x) + √3[tan(x)] - tan(x) - √3 = 0
Factor into
[-1 + tan(x)]*[√3 + tan(x)] = 0
which means
[-1 + tan(x)] = 0 and/or [√3 + tan(x)] = 0
Then
tan(x) = 1
tan-1(1) = pi/4 radians
For the other equation
[√3 + tan(x)] = 0
tan(x) = -√3
tan-1(-√3) = -pi/3
so that
x = pi/4 or -pi/3 in the interval [0, 2pi]
The tree died about 3357 years ago.
Explanation:
The half life of carbon - 14 is given by
where 


Substituting these values in the above equation, we get,

Taking In on both sides of the equation, we get,



Since, only 66% of Carbon - 14 remains after the time T.
Thus, we have,

Taking In on both sides of the equation, we get,



Thus, the tree died about 3357 years ago.
