integral of 2y-2

解答

\int 2 y - 2 d y

y^{2} - 2 y + C

求解步骤

\int 2 y - 2 d y

使用积分加法定则:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= \int 2 y d y - \int 2 d y

\int 2 y d y = y^{2}

\int 2 d y = 2 y

= y^{2} - 2 y

解答补常数

= y^{2} - 2 y + C

in v erse l a pl a ce \frac{1}{s ( s ^{2} + 6 π s + π ^{2} )}

\int \frac{3 tan ( x ) - 4 cos ^{2} ( x )}{cos ( x )} d x

\int ((x - 1)^{5} + 3 (x - 1)^{2} + 5) d x

\frac{\partial}{\partial x} (e^{x} (sin (y) - y))
