WebApr 12, 2024 · I am studying recursive formulas in the famous coins problem in dynamic programming. However, I cannot solve this variation where there is a constraint where each coin (a power of two) could be used at most twice. I know the recursive formula for the standard coin problem is as follows: WebIn this problem you will use variation of parameters to solve the nonhomogeneous equation t 2 y ′′ + 4 t y ′ + 2 y = 2 t 3 + 3 t 2 A. Plug y = t n into the associated homogeneous equation (with " 0 " instead of " 2 t 3 + 3 t 2"") to get an equation with only t and n.
