It is true that, in elementary mathematics, the two functions aren't the same because of domain issues. Example. Suppose we wish to solve the equation tanx = −1 for −π ≤ x ≤ π. A graph of the tangent function over this interval is shown in Figure 11. We know from ... This tangent line is a good linear approximation to f(x) near x1, so our next guess x2 is the point where the tangent line intersects the x-axis, as shown above ...
