inverselaplace s^2+6s+7

解答

的拉普拉斯逆变换

s^{2} + 6 s + 7

对于标准函数无解

求解步骤

L^{- 1} {s^{2} + 6 s + 7}

= 对于标准函数无解

x \to \frac{π}{2} lim (x)

d er i v a t i v e y = \frac{7 ln ( x )}{3 x + 4}

x \to \frac{1}{3} lim (3 x^{3} + 2 x^{2})

n or ma l y = \frac{x}{x ^{2} + 1}, at x = - 1

\frac{\partial}{\partial x} (2 x \cdot y - \frac{1}{2} x^{2})
