Question

how do i verify euler's formula

Answer 1

Verify? Pick a verifiable case and show that it works?

Answer 2

euler's formula is
=F+V=E+2
F is for faces
V is for vertices
E is for edges
Faces are the flat surfaces.
Edges are the lines that are formed in a polygon ( like lines in a rectangle,etc. )
Vertices are points joining these lines.

Answer 3

no i have to show that cos x + i sin x + 1 = 0

Answer 4

okay .-. i am no good at sin cos or tan so @campbell_st come back please c:

Answer 5

well just pick a solid...

say a square based pyramid...

5 faces

5 vertices

and 8 edges...

does that work in the formula...

try it with a cube

6 faces

8 vertices

12 edges

see if it works

Answer 6

i have gotten as far as cis x = -1

Answer 7

Try \(x = \pi\)
