integral from 5 to 8 of 1

\int_{5}^{8} 1

3

Solution steps

\int_{5}^{8} 1 d x

Integral of a constant:

\int a d x = a x

= [1 \cdot x]_{5}^{8}

Simplify

= [x]_{5}^{8}

Compute the boundaries:

3

= 3

\frac{\partial}{\partial x} (cos^{7} (x^{6} y^{6}))

\frac{d}{d x} (2 sin (2 x) - ln (3 x + 1))

\int \frac{8 ln ( x )}{x ^{2}} d x

\frac{d}{d x} (\frac{( 40 x ^{5} )}{e ^{x}})

t^{2} \frac{d y}{d t} - t = 1 + y + t y, y (1) = 4
