Answer:
Euler's method is a numerical method used in calculus to approximate a particular solution of a differential equation. As a numerical method, we have to apply the same procedure many times, until get the desired result.
In first place, we need to know all the values the problem is giving:
- The step size is 0.2; h = 0.2. This step size is a periodical increase of the x-variable, which will allow us to calculate each y-value to each x.
- The problem is asking the solution y(1), which means that we have to find the y-value assigned for x = 1, through the numerical method.
- The initial condition is y(0) = 9. In other words,
.
So, if the initial x-value is 0, and the step size is 0.2, the following x-value would be:
; then
;
; and so on.
Now, we have to apply the formula to find each y-value until get the match of
, because the problem asks the solution y(1).
According to the Euler's method:

Where
, and
;
.
Replacing all values we calculate the y-value assigned to
:
.
Now,
,
. We repeat the process with the new values:

Then, we repeat the same process until get the y-value for
, which is
, round to four decimal places.
Therefore,
.

The correct answer should be Choice B.
Scholarships and merit aid are the best way to earn money to go to college. They don't have to be paid back. When it comes to loans, you should select federal before non-governmental because the interest rates are usually lower on federal loans.
