maclaurin cos(x^4)

maclaurin

cos (x^{4})

1 - \frac{1}{2} x^{8} + \dots

Solution steps

Apply the Maclaurin Formula

= 1 + \frac{\frac{d}{d x} ( cos ( x ^{4} ) ) ( 0 )}{1 !} x + \frac{\frac{d ^{2}}{d x ^{2}} ( cos ( x ^{4} ) ) ( 0 )}{2 !} x^{2} + \frac{\frac{d ^{3}}{d x ^{3}} ( cos ( x ^{4} ) ) ( 0 )}{3 !} x^{3} + \dots

Evaluate Derivatives

= 1 + \frac{0}{1 !} x + \frac{0}{2 !} x^{2} + \frac{0}{3 !} x^{3} + \frac{0}{4 !} x^{4} + \frac{0}{5 !} x^{5} + \frac{0}{6 !} x^{6} + \frac{0}{7 !} x^{7} + \frac{- 20160}{8 !} x^{8} + \frac{0}{9 !} x^{9} + \frac{0}{10 !} x^{10} + \dots

Refine

= 1 - \frac{1}{2} x^{8} + \dots

\frac{d}{d x} ((ln (2 x)) d x)

x \cdot e^{- x}

\int 35 x^{4} d x

\frac{d}{d x} (\frac{3 + x}{1 - 3 x})

y = \frac{4 x}{1 + x ^{2}}, y = \frac{4 x ^{2}}{1 + x ^{3}}
