maclaurin e^{-x^2}

maclaurin

e^{- x^{2}}

1 - x^{2} + \frac{1}{2} x^{4} - \frac{1}{6} x^{6} + \frac{1}{24} x^{8} + \dots

Solution steps

Apply the Maclaurin Formula

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

Evaluate Derivatives

= 1 + \frac{0}{1 !} x + \frac{- 2}{2 !} x^{2} + \frac{0}{3 !} x^{3} + \frac{12}{4 !} x^{4} + \frac{0}{5 !} x^{5} + \frac{- 120}{6 !} x^{6} + \frac{0}{7 !} x^{7} + \frac{1680}{8 !} x^{8} + \dots

Refine

= 1 - x^{2} + \frac{1}{2} x^{4} - \frac{1}{6} x^{6} + \frac{1}{24} x^{8} + \dots

\int \frac{2 x}{( x ^{2} + 1 ) ^{2}} d x

\int_{\frac{π}{6}}^{\frac{π}{4}} cos (x) d x

s (t) = 5^{t}

\frac{d}{d x} (- 3 tan (x))

\int_{7}^{8} (\frac{7}{x ^{2}} - 1) d x
