integral of 1/(x^{sqrt(2))}

解答

\int \frac{1}{x ^{2}} d x

- (2 + 1) x^{- 2 + 1} + C

求解步骤

\int \frac{1}{x ^{2}} d x

使用幂法则

= - (2 + 1) x^{- 2 + 1}

解答补常数

= - (2 + 1) x^{- 2 + 1} + C

x \to 0 lim (\frac{tan ^{2} ( x )}{1 - cos ( x )})

d er i v a t i v e \frac{x ^{2}}{x + 2}

\frac{\partial}{\partial x} (x y + \frac{1}{x} + \frac{1}{y})

t an g e n t f (x) = 9 - 6 x, at x = - 1
