val i : complex The square root of ~ 1.0 val fromReal : real - > complex Converts from an real to complex . Duplicate documents may not be available for up to 48 hours and research of time missed / hours worked history or employment history may be two weeks . Criteria for such ratings shall include but not be limited to ( a ) The applicant 's overall grade point average and course review , ( b ) evaluations by cooperating teachers and supervisors of the applicant 's behavioral and classroom management , interactive skills , communication skills , planning and presentation in the classroom . The enrollment period may be extended for those certification areas in which there is a shortage of teacher applicants or an underrepresentation of minority teacher applicants in the Madison Metropolitan School District . Further , if you're predicted run time is logarithmic , then you should use a log scale on the data size , so that the theoretically predicted curve is a straight line - - it 's easy to detect a deviation from a straight line , but hard to look at a curve and say " this is logarithmic " ( it could be some type of root and look much the same ) . For instance , you should plot search / insertion / deletion times per operation rather than cumulatively ( many of you even thought that the cumulative values should be logarithmic and made comments about being surprised at observing an apparently linear behavior , when in fact you should have expected n log n behavior in the cumulative values ) and you should use a log scale on the data size , so that the theoretically predicted curve would be a straight line - - it 's easy to detect a deviation from a straight line , but hard to look at a curve and say " this is logarithmic " Evaluating data : timing alone may simply reflect errors in the code or errors in data generation or unusual data patterns generated by your test driver ( many of you inserted , then deleted in the same order in search trees , thereby making delete look much too good ) .
