limit as (x,y) approaches (1,2) of 1+x+y

(x, y) \to (1, 2) lim (1 + x + y)

4

Solution steps

(x, y) \to (1, 2) lim (1 + x + y)

Plug in the value

(x, y) = (1, 2)

= 1 + 1 + 2

Simplify

= 4

f (x) = x^{3} - 5 + 2 x

x \to \infty lim (e^{- x})

\frac{\partial}{\partial x} (\frac{2 x - 3}{x y})

7 - 3 u

\frac{\partial}{\partial y} (x^{2} y + 3 y + x^{2} y^{3} - 4 x)
