In fourth order Runge-Kutta method
K 4
is given by
Answer
k4 = hf(xn th,yn + kz)
k4 = hf(xn + 2h, + 2kz)
None of the given choices
k4 = hf(x, — h,Yn — kz)

In the fourth-order Runge-Kutta method,  k_4 , ￼ is given by the formula:
k_4 = h \cdot f\left(x_n + h, y_n + k_3\right)
￼
However, from the options you’ve provided, it seems that none of them correctly represent the standard formulation for  k_4  ￼.
To clarify based on standard notation:
•	￼  k_4  depends  on the function evaluated at the next step after adding the entire step size  h  to  x_n  and the third slope  k_3  to  y_n .

If the options don’t include the correct form for  k_4 ￼, then the answer would be None of the given choices.

Answer
^2-“/”“” З’Уп 3’
k2 = 45(-12.30-42)

In the fourth-order Runge-Kutta method, ￼ is computed using the following formula:
￼
k_2 = h \cdot f\left( t_n + \frac{h}{2}, y_n + \frac{k_1}{2} \right)
where:
•	￼  h  is the step size
•	￼  t_n  is the current value of the
•	￼  y_n  is the current value of the dependent variable,
•	￼  k_1 = h \cdot f(t_n, y_n)  is the first slope.

The formula you provided seems to be incorrect or misformatted. If you have specific terms or a function f(t, y) ￼, please clarify or correct the notation so I can provide the accurate calculation for ￼ in your context.
