 Simplify 1/2^i 2018-01-28 Deepak pose la question :How do I simplify this complex equation: z=1/(2^i)Penny Nom lui répond. Euler's polyhedron formula 2016-05-20 Antonia pose la question :why does not cylinders follow Euler's polyhedron formula ( V-E+F=2) ?? if a cylinder has 3 faces, 2 edges and 0 vertices it doesn't follow Euler's formula???Penny Nom lui répond. A mythical soccer ball 2011-10-27 Joel pose la question :We've been working on this problem diligently and can't seem to come up with the answer book's answer. We think it may be wrong, yet want to check it with an expert. Here goes. The school's new soccer balls are covered with 64 regular hexagonal panels. Each hexagon measures 2 inches between opposite corners and 1.5 inches between opposite sides. What is the total surface area of the soccer ball?Robert Dawson and Lorraine Dame lui répond. Vertices and sides of a polygon 2011-03-04 RINA pose la question :My questions is : would a vertices and sides of a polygon be the same number.  For example, a octagon it has 8 points and 8 sides. Am i correct?Robert Dawson lui répond. i^i 2010-11-21 trale pose la question :Can we use e^ix=cosx+isinx for finding i^i like that: x= pi/2 => e^(ipi/2)=0+i then [e^(ipi/2)]^i=i^i.then we find i^i= 0,207879576.... is it true? can we give value for x for free?thank you.Harley Weston lui répond. Faces, edges and vertices 2009-02-04 sheila pose la question :what is the relationship between the number of faces and the number of edges of a triangular pyramid ?Penny Nom lui répond. I have 6 vertices and 10 edges 2008-10-20 Jacquelin pose la question :I have 6 vertices and 10 edges. One of my faces is a regular polygon.Chris Fisher lui répond. A shape 2008-04-03 Joshua pose la question :what shape has 4 faces, 4 corners and 9 edges.Penny Nom lui répond. What constitutes a face for a geometric solid? 2007-02-14 Erica pose la question :What constitutes a face for a geometric solid? We have been getting conflicting answers from different textbooks. Some teachers are saying that cylinders and cones do not have faces. I'm thinking that cylinders have 2 and cones have 1. Please enlighten me. Thanks!Walter Whiteley lui répond. Is there a solid shape with 5 faces, 8 edges, and 4 vertices? 2006-02-11 Annie pose la question :Is there a solid shape with 5 faces, 8 edges, and 4 vertices?Penny Nom lui répond. Faces 2001-02-21 Sandy pose la question :How many faces are there on a sphere? What are the faces of a cone? What is the definition of a "face" of a 3D object? Walter Whiteley lui répond. Euler's Formula 2000-11-11 Denise Roberts pose la question :I'm trying to design a unit (possibly involving a Webquest) on Polyhedra and I cannot find a formula I once used. The formula involved the number of vertices (V), edges (E), and faces (F) of the polyhedra.Walter Whiteley lui répond.
