integral of r^2-x^2

Solution

\int r^{2} - x^{2} d x

Solution

r^{2} x - \frac{x ^{3}}{3} + C

Solution steps

\int r^{2} - x^{2} d x

Apply the Sum Rule:

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

= \int r^{2} d x - \int x^{2} d x

\int r^{2} d x = r^{2} x

\int x^{2} d x = \frac{x ^{3}}{3}

= r^{2} x - \frac{x ^{3}}{3}

Add a constant to the solution

= r^{2} x - \frac{x ^{3}}{3} + C

derivative of sqrt(4-3x)

\frac{d}{d x} (4 - 3 x)

(19xy^2+11y)+(19x^2y+11x)((dy)/(dx))=0

(19 x y^{2} + 11 y) + (19 x^{2} y + 11 x) (\frac{d y}{d x}) = 0

y^{''}+4y=sec(2x)

y^{^{''}} + 4 y = sec (2 x)
