Requirement:
Is it what type of transportation problem? Discuss the other types of it.
The penalty costs for not satisfying demand at the warehouses D, E, and F are TK. 5,
3, and 2 per unk respectively. Determine minimum transportation cost by using Lest
Cost Method (LCM)
25.18 The following is an initial-value, second-order differential equation:
d²x + (5x) dx + (x + 7) sin (wt) = 0
dt²
dt
where
dx (0)
(0) = 1.5 and x(0) = 6
dt
Note that w= 1. Decompose the equation into two first-order differential equations. After the
decomposition, solve the system from t = 0 to 15 and plot the results of x versus time and dx/dt versus time.
