Calc1 231 W1 T3 - Total Differential Approximation Current Grade: 7.4/2o.o Remaining Time: 95:33:05 _ Question 3 Evaluating integrals can be difficult. So let's instead use the total differential approximation to approximate the Sine Integral 4 points :1: sin ( t) $m=/ ta 0 near the point A = [37 Si(3)] z [3,1849]. The differential approximation to Si near 3 is given by the formula ma~mw+ymwa Since Si, (3) = ,we have the linear approximation to Si(:c) near a: = 3: w z :1 a a - . Use the linear approximation to evaluate (to 3 decimal places) SW - 0 Use the plot below (drag the slider to the appropriate value) to evaluate (to 3 decimal places) Si(2.9) m ' 1.842 oJ.
