- Solve the following differential equations. You may have to leave your answer implicit. 1) y'=(y-4x)/(x-y) is it isobaric? 2) x(1+y2)y'+x2y3=0 hint: try the integrating factor λ(x)= 1/xy36. A reciprocal-lattice vector has a dimension equal to the reciprocal of length, for example, cm-'. Is it meaningful to compare the magnitudes of a direct-lattice vector R with a reciprocal-lattice vector G? Is it meaningful to compare their directions? If the latter answer is yes, find the angle between R and G in terms of their components in a cubic crystal. What is the angle between R = [111] and G = [110]?p9C.1 Familiarity with the magnitudes of overlap integrals is useful when con- sidering bonding abilities of atoms, and hydrogenic orbitals give an indication of their values.
