Consider the differential equationy '' − 2y ' + 26y = 0; ex cos 5x, ex sin 5x, (−[infinity], [infinity]).Verify that the given functions form a fundamental set of solutions of the differential equation on the indicated interval. The functions satisfy the differential equation and are linearly independent sinceW(ex cos 5x, ex sin 5x) = ≠ 0for−[infinity] < x < [infinity].

Each of the walls of a room with square dimensions has been built with two pieces of sheetrock, a smaller one and a larger one. the length of all the smaller ones is the same and is stored in the variable small. similarly, the length of all the larger ones is the same and is stored in the variable large. write a single expression whose value is the total area of this room. do not use any method invocations.
