Linear approximations are useful if we want to calculate values of a function that a calculator can’t handle with its limited number of digits. Linear approximations can be used to interpolate between data points. Equation for the tangent line (linear approximation) of a function f(x) at x = x0: y = L(x) = f(x0) + f … ................
