derivative of x+y+2

解答

\frac{d}{d x} (x + y + 2)

\frac{d y}{d x} + 1

求解步骤

\frac{d}{d x} (x + y + 2)

使用微分加减法定则:

(f \pm g)^{'} = f^{'} \pm g^{'}

= \frac{d x}{d x} + \frac{d y}{d x} + \frac{d}{d x} (2)

\frac{d x}{d x} = 1

\frac{d}{d x} (2) = 0

= 1 + \frac{d y}{d x} + 0

化简

= \frac{d y}{d x} + 1

\int \frac{3 x ^{2} + 2 x + 4}{x ^{3} + 4 x} d x

\frac{d r}{d θ} + r tan (θ) = 3 tan (θ)

d er i v a t i v e e^{5} + ln (7)

\int \frac{1}{3 x + 4} d x

y^{^{'}} + x y = a
