Given the IVP
dy
- =x² – sin y, y(0) =.5
dx
Estimate y(0.4) using 4th order RK method with step size h=0.2.
For a chemical reaction, the rate of change of the concentration of component
A is described by the differential equation:
dCa = -k,C - k,C,
dt
Where
CA concentration of A (moles/liter)
ki rate constant = 2.7 hr1
k2 rate constant = 0.8 hr-' (moles/liter)1
The initial concentration of A is: CA (0) = 3.0 mole/liter
Determine the concentration of A at t = 1/4 hr, 1/2 hr, using the fourth order
Runge-Kutta method, with h= 1/4 hr.
