Question 34

Multiple Choice

Use the Taylor polynomials for the sine and cosine functions to find a rational function with a degree 5 numerator and no fractional coefficients that approximates the tangent function near 0.


A) R(x) =x5+24x4120x3x46x2+120R(x) =\frac{x^{5}+24 x^{4}-120 x^{3}}{x^{4}-6 x^{2}+120}
B) R(x) =x520x3+120x5x460x2+120R(x) =\frac{x^{5}-20 x^{3}+120 x}{5 x^{4}-60 x^{2}+120}
C) R(x) =30x46x2+120120x3+x5R(x) =\frac{30 x^{4}-6 x^{2}+120}{-120 x^{3}+x^{5}}
D) R(x) =120x524x3+x30x460x2+120R(x) =\frac{120 x^{5}-24 x^{3}+x}{30 x^{4}-60 x^{2}+120}
