Question

Using Euler's method, find the secondapproximate value of y corresponding to ch dx = x + y and y = 1 when x = 1, given that x = 0​

Answer 1

Answer:

By Euler's formula the numbers of faces F, of vertices V, and of edges E of any convex polyhedron are related by the formula F + V = E + 2. In the case of a cuboid this gives 6 + 8 = 12 + 2; that is, like a cube, a cuboid has 6 faces, 8 vertices, and 12 edges.

Vertices: 8

Edges: 12

Dual polyhedron: Rectangular
