Array of values of a function : How to use it?
The values calculator returns the table of values of a function obtained from an initial value and the difference between two consecutive values (steps).
Syntax :
array_values(function;initial_value;number_values;step)
Examples :
array_values(4+x^2;0;10;1)
The calculator is able to calculate online the values of a function from an initial value and a step (difference between two consecutive values).
Calculating the values of a function
The calculator can be used to determine the values of a function.
For example, to obtain an array of values for the function defined by f(x)=x2+1, enter : array_values(x^2+1;0;10;1). The array will contain 10 values, which are calculated by taking the value 0 as the initial value and a step of 1. It is possible to change the initial value, the number of values (limited to 100) and the step to get the desired array of values. The calculations of the values of the functions are realized in exact form but also in approximate form as shown in this example array_values(x^2/2+1;0;10;1).
