(Okay, a calculator might save you some headaches down the line.) When both numbers are expressed in their standard forms, the trick is to multiply the numerator and the denominator by the conjugate of the latter:The denominator becomes a squared modulus of the divisor. You’ll learn more ...
Calculator techniquesComplex rootsComplex domain computation skillsNumerical techniquesReal numbers are something which are associated with the practical life. This number system is one dimensional. Situations arise when the real numbers fail to provide a solution. Perhaps the Italian mathematician Gerolamo ...

4.1.4 Complex conjugate roots When the roots are complex numbers—λ1=p+qi and λ2=p−qi, where p and q are real numbers—the two corresponding solutions of the differential equation ay″+by′+cy=0 are y1(t)=e(p+qi)t and y2(t)=e(p−qi)t. At this point, a crucial fact...

15). However, there were exceptions, for instance, the total numbers of SMGCs were identical in the narrow host-range species C. kahawae and the closely related species with a broad host range, C. cigarro. Nonetheless, C. kahawae displayed an expansion in non-ribosomal peptide synthetase (...
Cardinal numbers describe the size of a collection of objects; two such collections have the same (cardinal) number of objects if their members can be matched in a one-to-one correspondence. Ordinal numbers refer to position relative to an ordering, as first, second, third, etc. The finite...
