tailieunhanh - Ebook Engineering economy (8th edition): Part 1

(BQ) Part 1 book "Engineering economy" has contents: Foundations of engineering economy, factors - how time and interest affect money, combining factors and spreadsheet functions, nominal and effective interest rates, present worth analysis, annual worth analysis,.and other contents. | Format for Spreadsheet Functions on Excel® Present worth: Contents of ( ) = PV(i%, n, A, F) for constant A series; single F value = NPV(i%,second_cell:last_cell) + first_cell for varying cash flow series Future worth: = FV(i%,  , A, P) n for constant A series; single P value Annual worth: = PMT(i%,  n,  ,  F ) P for single amounts with no A series = PMT(i%, n, NPV) to find AW from NPV; embed NPV function Number of periods (years): = NPER(i%,  A, P,  ) F for constant A series; single P and F (Note: The PV, FV, and PMT functions change the sense of the sign. Place a minus in front of the function to retain the same sign.)
