f(1) and f(-2) means to replace x in the equation with the number inside the parenthesis and then solve.

f(1) = (1)^2 -3(1) -f = 1 -3 -f = -2-f

f(-2) = (-2)^2 -3(-2) -f = 4 + 6 - f = 10-f

Use Euler’s method with two steps to estimate y(1) if y(x) is the solution to dy dx = x + y, y(0) = 1. Write your answer in the
tresset_1 [31]

Answer:

1.5

Step-by-step explanation:

The Euler's method is a common approximation method for the solution of differential equations. It can be used to obtain an approximate value of a given function. The Euler's formula is:

y_{n} = y_{n-1} + hF(_{x_{n-1},y_{n-1}})

Therefore, n =1 will give:

y_{1} = y_{0} + hF(x_{0},y_{0})

h is the step size and it is equivalent to \frac{x_{1}-x_{2}}{2} = \frac{1-0}{2}=\frac{1}{2}

F(x_{0},y_{0}) = x_{0} + y_{0} = 0 + 1 = 1

y_{1} = 1 + (0.5)(0+1) = 1 + (0.5)(1) = 1 + 0.5 = 1.5
