Use linear approximation, i.e. the tangent line, to approximate 3/253 as follows: Let f(3:) = . The equation of the tangent line to f(:.r:) at a: = 25 can be written in the form 3; 2 ms: + b Using this, we find our approximation for 25.3 is NOTE: For this part, give your answer to at least 9 significant gures or use an expression to give the exact
