area-1/2 x^2+5/2 x-2,[-2,7]

area

- \frac{1}{2} x^{2} + \frac{5}{2} x - 2, [- 2, 7]

\frac{99}{4}

Decimal Notation

24.75

Solution steps

Apply the area formula:

\int_{- 2}^{7} - \frac{1}{2} x^{2} + \frac{5}{2} x - 2 d x

Solve

\int_{- 2}^{7} - \frac{1}{2} x^{2} + \frac{5}{2} x - 2 d x : \frac{99}{4}

The area is:

= \frac{99}{4}

f (x) = \frac{1 + x}{( 2 x ^{2} + 1 ) ^{2}}

y^{^{'}} + 2 y = 0, y (1) = 1

y y^{^{'}} = \frac{x}{x ^{2} + 1}

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

e^{t} t
