Answer:

employees.get(0)

In the programming, the index of ArrayList start from zero.

So, the element start storing in the ArrayList from the zero index.

get() is the function which is used to retrieve or getting the value in the

ArrayList.

The function employees.get(0), it retrieve the element of zero index.

The function employees.get(1), it retrieve the element of first index.

The function employees.first(1), it is wrong calling.

The function employees.get(), it is wrong calling. you have to enter the index value inside the get().

Y'+2y = 5-e^(-4x), y(0)=-11

Anastaziya [24]

Answer:

see attached

Explanation:

A differential equation solver says the exact solution is ...

y = 5/2 -14e^(-2x) +1/2e^(-4x)

The y-values computed by Euler's method will be ...

y = ∆x·y' = 0.1(5 - e^(-4x) -2y)

The attached table performs these computations and compares the result. The "difference" is the approximate value minus the exact value. (When the step size is decreased by a factor of 10, the difference over the same interval is decreased by about that same factor.)
