Estimations with linear approximation ?Use linear approximations to estimate the following quantities. Choose a value of a to produce a small error. ?146

Solution 15E STEP 1 Linear approximation is a method of estimating the value of a function,f(x),near a point x=a,using the formula L(x) = f(a)+f (a)(xa) STEP 2 Here,let f(x) = ;and choose a=144 We get f (x) = 1 2x 1 1 1 f(a) = 144 = 12and f (a) = 2 144= 2×12= 24 Therefore...
