Use linear approximation, i.e. the tangent line, to approximate [1/0.204]

[Jkhhkgk Kbhbgh]

as follows: Let f(x) = [1/x] and fin? Use linear approximation, i.e. the tangent line, to approximate [1/0.204] as follows: Let f(x) = [1/x] and find the equation of the tangent line to f(x) at a "nice" point near 0.204. Then use this to approximate [1/0.204].
