The Tramadol has been a major topic on this site, some good, some bad, and seems almost everyone has an opinion about it one way or the other. My pm dr. gave me some sample of Lyrica which ( besides the weight gain ), it works very well for the nerve pain. It helps me sleep as well.
Trigonal pyramidal molecular geometry. In chemistry, a trigonal pyramid is a molecular geometry with one atom at the apex and three atoms at the corners of a trigonal base, resembling a tetrahedron (not to be confused with the tetrahedral geometry). When all three atoms at the corners are identical, the molecule belongs to point group C3v.
A rectangular pyramid is a solid which has a rectangle shape at the base and the four faces on the four sides of the rectangle which are isosceles triangles meeting at a point in the heavens. So the rectangular pyramid has 5 faces - one a rectangle at the base and the other four are isosceles triangles on the four faces. It has 8 edges - four at the base and four above the base and meeting at a common point.
