2 (ln (- 1) + 1)

2 ln (- 1) + 2

求解步骤

2 (ln (- 1) + 1)

使用分配律:

a (b + c) = ab + a c

a = 2, b = ln (- 1), c = 1

= 2 ln (- 1) + 2 \cdot 1

数字相乘:

2 \cdot 1 = 2

= 2 ln (- 1) + 2

e x p an d (5 + 11 x) x^{4} e^{11 x} + 3

e x p an d (3, 1) y (4, - 11)

e x p an d (1 - cos (x))^{2} + (sin (x))^{2}

e x p an d \frac{a}{s ( s ^{2} + a ^{2} )}

e x p an d x (cos (x) - 1)
