To find the limit of the function e^sqrt(3x^2+2y^2) as (x,y) approaches (5,4), we can use the epsilon-delta definition of a limit. Let's denote the limit as L.

If the limit exists, it means that for any positive value of epsilon (ε), there exists a positive value of delta (δ) such that if the distance between (x,y) and (5,4) is less than delta, then the distance between e^sqrt(3x^2+2y^2) and L is less than epsilon.

To proceed with the calculation, we need to find the value of L. Let's substitute the values of x and y with 5 and 4, respectively, in the given function:

e^sqrt(3(5)^2+2(4)^2) = e^sqrt(75+32) = e^sqrt(107)

Therefore, the limit L is e^sqrt(107).

Now, to prove that the limit exists, we need to show that for any positive epsilon (ε), there exists a positive delta (δ) such that if the distance between (x,y) and (5,4) is less than delta, then the distance between e^sqrt(3x^2+2y^2) and L (e^sqrt(107)) is less than epsilon.

To do this, we need to analyze the function and find an appropriate delta value. However, without further information or constraints on epsilon (ε), it is not possible to determine a specific delta value.

In conclusion, the limit of e^sqrt(3x^2+2y^2) as (x,y) approaches (5,4) is e^sqrt(107), provided that an appropriate delta value can be determined for any given epsilon (ε).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
