Solved: The approximation sin x x It is often useful to
Chapter 1, Problem 64E(choose chapter or problem)
The approximation sin x x It is often useful to know that, when x is measured in radians, si x x for numerically small values of x. In Section 3.11, we will see why the approximation holds. The approximation error is less than 1 in 5000 if |x| < 0.1.a. With your grapher in radian mode, graph y = sin x and y = x together in a viewing window about the origin. What do you see happening as x nears the origin?b. With your grapher in degree mode, graph y = sin x and y = x together about the origin again. How is the picture different from the one obtained with radian mode?
