Linear and Quadratic Approximations In Exercises 85-88, use a graphing utility to graph the function. Then graph the linear and quadratic approximations
\(P_{1}(x)=f(a)+f^{\prime}(a)(x-a)\)
and
\(P_{2}(x)=f(a)+f^{\prime}(a)(x-a)+\frac{1}{2} f^{\prime \prime}(a)(x-a)^{2}\)
in the same viewing window. Compare the values of f, \(P_{1}\), and \(P_{2}\) and their first derivatives at x = a. How do the approximations change as you move farther away from x = a?
Function Value of a
f(x) = 2(sin x + cos x) \(a=\frac{\pi}{4}\)
Text Transcription:
P_1(x)=f(a) + f’(a)(x-a)
P_2(x)=f(a) + f’(a)(x-a)+1/2 f’’(a)(x-a)^2
P_1
P_2
a=pi/4
