integral from 1 to 2 of 8x^3+3x^2

解

\int_{1}^{2} 8 x^{3} + 3 x^{2} d x

解

37

解答ステップ

\int_{1}^{2} 8 x^{3} + 3 x^{2} d x

総和規則を適用する:

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

= \int_{1}^{2} 8 x^{3} d x + \int_{1}^{2} 3 x^{2} d x

\int_{1}^{2} 8 x^{3} d x = 30

\int_{1}^{2} 3 x^{2} d x = 7

= 30 + 7

簡素化

= 37

(\partial)/(\partial x)(x^2+y^2-2x-2y)

\frac{\partial}{\partial x} (x^{2} + y^{2} - 2 x - 2 y)

面積 f(x)=2sin(x)+sin(2x),y=0,0<= x<= pi

a re a f (x) = 2 sin (x) + sin (2 x), y = 0, 0 \leq x \leq π

x^{^{'}} = x - 15
