Derivative of a function
The derivative of a function up to the 20th order is calculated
Enter:
1) The expression of the function WITHOUT entering y =
2) The order of the derivative
3) If necessary, enter the value in which to calculate the derivative (optional)
To enter the expressions you must use the app keyboard
Only certain functions appear on the keyboard by default. To display the keys related to the other functions, press the red keys (fn...for other functions).
By inserting the functions via the app keyboard, the names of the functions (eg sqrt () for the square root) will be inserted in the input box. Once the function has been entered, the cursor will be positioned within the round brackets (sqrt(|)) in order to write the function argument, e.g. √5 write sqrt (5).
The piecewise functions must be written according to the following example:
The following results are shown;
1) All derivatives up to the required order including their domain and the domain of the function
2) The graph of the function and of the requested derivative
3) The value of the derivative at the requested point (if it has been inserted)
The steps to get the derivatives are not shown
