limit as x approaches 4 of xsqrt(20-x^2)

x \to 4 lim (x 20 - x^{2})

8

Solution steps

x \to 4 lim (x 20 - x^{2})

Plug in the value

x = 4

= 4 20 - 4^{2}

Simplify

4 20 - 4^{2} : 8

= 8

\frac{\partial}{\partial x} (12 x y^{2})

\int_{0}^{1} ((x^{2} + 1) e^{- x}) d x

f (x) = cos (\frac{π}{x})

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

\int_{0}^{3} (x + 2) d x
