How to Apply Advanced Spreadsheet Computations

This video demonstrates how to define a function in ZCubes and do the computations for a series of values for parameters easily. You will understand how ZCubes differentiates itself from Excel or other typical spreadsheets in computing values for a set of data in a spreadsheet by creating functions. You can enable a function to handle array of values using arrayfy and a series of values can be passed as parameters.

Finding velocity : Final velocity (v) of an object equals initial velocity (u) of that object plus acceleration (a) of the object times the elapsed time (t) from u to v. For standard gravity, a = 9.80665 m/s2.

1. To find the final velocity (V), use the ZCubes code as-
$V:=u+a*t;$
$V(1,9.8,1)$

displays the result as 10.8.

2. To find the final velocity(V) for array of values of 't' from 1 to 30, use the following ZCubes code as-
$V:=u+a*t;$
$Varr;$ //typing arr and pressing Shift+Space key gives an character '#'
$V(1,9.8,1..30)$

displays the final velocity values with varying inputs of time as:

u      t       V
