To find the equation of the tangent to the curve y=1/(3x) at the point where x=1/6, we need to find the slope of the tangent line at that point.
First, we find the derivative of the function y=1/(3x) using the power rule for differentiation.
The derivative of y with respect to x is given by dy/dx = -1/(3x^2).
Next, we substitute x=1/6 into the derivative to find the slope of the tangent line at that point.
dy/dx = -1/(3(1/6)^2) = -1/(3(1/36)) = -1/(1/12) = -12.
Therefore, the slope of the tangent line at x=1/6 is -12.
Using the point-slope form of a linear equation, y - y1 = m(x - x1), where (x1, y1) is the point on the curve, we substitute x=1/6, y=1/(3(1/6)) = 2 into the equation.
y - 2 = -12(x - 1/6).
Simplifying the equation, we get y - 2 = -12x + 2.
Rearranging the equation, we find the equation of the tangent line to be y = -12x + 4.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
