e^4t= 1/2

解答

e^{4} t = \frac{1}{2}

t = \frac{1}{2 e ^{4}}

十进制

t = 0.00915 \dots

求解步骤

e^{4} t = \frac{1}{2}

两边除以

e^{4}

t = \frac{1}{2 e ^{4}}

\frac{1}{3} \cdot (x - 2) + \frac{1}{4} \cdot (x + 3) = \frac{1}{5} \cdot (x + 4) + 15

so l v e f or x, y^{1} + y + y^{2} \cdot (sin (x) - cos (x)) = 0

x - \frac{1}{10} = 997.5

so l v e f or x, e^{f} (x) + f - x = 1

so l v e f or x, \frac{x}{2} + \frac{( 3 y )}{5} = - 1
