(dy)/(dt)=7y^2t^3,y(2)=3

解答

\frac{d y}{d t} = 7 y^{2} t^{3}, y (2) = 3

y = - \frac{12}{21 t ^{4} - 340}

求解步骤

\frac{d y}{d t} = 7 y^{2} t^{3}

求解可分离方程:

y = - \frac{12}{21 t ^{4} - 340}

y = - \frac{12}{21 t ^{4} - 340}

\int_{1}^{3} \frac{t}{3 + t ^{2}} d t

\int \frac{2 x + 3}{x + 2} d x

\frac{d}{d t} (a t - tanh (a t))

\int_{0}^{6} - 2 x d x

\frac{d}{d x} (\frac{2}{9} x^{3} + 3 x + cos (x) + 1)
