No slide movement needed.Any number on an LL scale has its reciprocal directly opposite on thecorresponding reciprocal Log Log scale, because e to the x power is the reciprocalof e to the minus x power. Numbers on LL2 are reciprocals of numbers onLL/2. LL3 and LL/3, LL1 and LL/1, LL0 and LL/0 have the same relationship.Note: On some silde rules, the reciprocal Log Log scales are called LL00,LL01, LL02, LL03.Inverse of ProductFind: __ __1____4 X 0.07Cursor to 4 on DSlide to 7 on CIInverse of NumberFind: Inverse of 0.144Left index of C to l44 on DFind: Inverse of 8Right index of C to 8 on DAnswer: 3.57 on C atright index of DAnswer: 6.94 on C atright index of DAnswer 0.125 on C atleft index of D
