化简 5t(x)x^{''}+(t(x)-10)x^'-x

解答

化简

5 t (x) x^{^{''}} + (t (x) - 10) x^{^{'}} - x

求解步骤

5 t (x) x^{^{''}} + (t (x) - 10) x^{^{'}} - x

去除括号:

(a) = a

= 5 t x x^{^{^{''}}} + (t x - 10) x^{^{^{'}}} - x

e x p an d A (2, - 3)

e x p an d \frac{3 x x ^{2} + 1}{( x ^{2} - 9 ) ( - x ^{2} + 2 x - 3 )}

e x p an d P (0, - 3) Q (- 1, 7)

\frac{\partial}{\partial x} ((z) (yz - z^{2} + x n y))

e x p an d cos (2 (t - π))
